Well, as a Canadian, I can't claim to know all about those. But let's see...
1. Giving lots of money...Comcast? Wasn't that part of the promise (and it wasn't just Comcast, it was AT&T and others) to expand broadband or wireless broadband via 5G to every American? Do you think he could do that without involving the nation's experts in those technologies -- and do you think he could (or should) force them to do it for free? There was actually much more to the initiative than that. He paid certain people's internet through a government plan. It was a huge initiative. And it costs many, many, many, many billions. Comcast and ATT are probably rich now. Think about how the money could have been used on more, broad stimulus for Americans.
2. Empty, unnuanced words in address to the LGBT+ community that doesn't do it proper justice? But didn't he reverse the transgender military ban from the Trump administration? That's a concrete step, and it is within his power. Much else comes under states' rights -- so what would you have him do other than encourage with words and arguments? Violate states' rights? Transgender is a huge issue. Reversing the ban is simply not enough. It's a drop in a mega sized bucket. Things may have actually gotten worse for some transgender people since Biden took office.
3. Too much focus on student loans, not enough focus on closing up loop-holes in government? But really, didn't he promise to do something about student loans? So shouldn't he focus on that -- as a promise? But why not be a little specific: what "loop-holes in government" are you referring to that you think he should close up? And do you have a suggestion as to how you think he should do it? Too much focus. Once he realized that it wouldn't fly, he should have focused energy on something else. As for the loop-holes, they should patch all the things which allowed crazy things to happen under Trump, and they need to be closed before the election, honestly. A couple of loop-holes have already been addressed, though.
4. Too strong a focus on capitalism? That, I'm afraid, is something he should be praised for. It is impossible for a society to create wealth without a basic underpinning of capitalism -- of privacy of ownership, and the ability to profit from one's own genius, entrepreneurial spirit, risk-taking and effort. Yes, more could be done about social concerns, but that is not the American way right now, is it? Read so many other threads in these forums, and every time the word "social" comes up, endless hysterical posts screaming "the end of America" follow inevitably. I think you're getting a distorted view of the issue based on certain posts, but I could be wrong. There's a certain fear in America now, and change is one of them. So of course these people might be scared of changing the system.
5. Right wing to the point that he sometimes misses the picture, or speaks about delicate subjects in an unnuanced way? I'd need some examples about what you mean there. (As a Canadian, everbody in the USA is to the right of my views -- but Joe Biden far less than so many others.) We need unity in this time, I feel, even if it's unity on one side. I see Biden as too right-wing, uncharismatic, and unnuanced to bring much energy, at least at this point. I'm saying that the bar needs to be set high now for President. We need another Obama, but much better. One who doesn't make the same mistakes.
6. Talks too much about what he wants to do. His actions should speak louder? The "promises kept" that I posted, as well as the even more promises still in progress and promises stymied by Republican opposition ARE his actions. But it is the leader's job not only to tell people about what he wants to do, but to tell them often, to communicate -- to paint the "richly-imagined future" so as to bring the majority on-board. No President can do it all by himself (and hopefully, herself one day). The job is much, much more about getting everybody engaged. And that's communication. He's not a real good communicator, though, I feel. In such a case, why waste much energy talking? It's not going to unite anyone.
7. Hasn't done enough to convince voters the dangers of Trump, and when he does speak about it, he speaks about it in a way which turns off both sides? Trump has 91 indictments before the courts at the moment -- and I think it would be very wrong for a sitting President to jump into that fray. He must, in very fairness to the justice system, be very, very careful in what he says, how he says it. I think it is far, far better for him to focus on his vision for America's future (whether you agree with that vision or not) than on the mistakes of its past. Biden is neither careful nor stays out of fanning the flames. If you haven't seen that, I can understand, since you may not get all speeches in Canada (I'm not sure). So he has covered some of these subjects before, and they were a strike-out and a huge miss each time. I'd be surprised if TV stations even wanted to cover them much, in general.
8. Has a short fuse sometimes when it comes to debate and difficult subjects? Again, I would need examples before I could respond. I have not seen them. However, I will say this -- he is a human being, and it is in the nature of every human being that the more difficult a subject becomes, the more likely that his amygdala will hijack his responses. Even Speaker McCarthy, the other day, yelled to his caucus in very real anger "bring the F****** motion!" And that, I think, was an amygdala hijack. Much like the one he had on the House floor after vote 13 on his Speakership. There are news stories about Americans with legitimate concerns asking him hard questions in person, and him getting mad and telling them off, even telling them to "vote for the other side [if you want to be that way]
