Can you provide some specific examples of people abusing their free speech?
Trump getting gag orders because he is making veiled threats to those involved in the court cases. And look at Trump's big lie about election fraud, and all those who believe im, and repeat his lies. That is all deliberate abuse of speech to get an outcome that is corrupt. Ideally the freedom of speech is that Trump can lie about election fraud, and the citizens follow the facts and realize he is a liar, and to be condemned. No, his base was duped, and they nominated him because he abused this freedom. If he wins, the freedom of speech will surely be curtailed once he is in power.
If you deliberately lie to your spouce about where you were last night, that isn't a speech issue. But the higher profile a person is, and they use their influence to deliberately lie, it is an abuse of the freedom of speech. It's worse today thsan back when Nixon lied, because there wasn't the disinformation network as we have today. So when Trump lies it gets defended in ways it never did before, and it is up to individuals to understand what is deceptive and lying. But we see that many do not have any such skill, or the will, to understand true from lies.
I would agree that social media often contains speech that you and I would agree is very offensive.
I'm not talking about offensive, as there is too much eye of the beholder at play. Look at the Muslims wo attacked Charlie Hebdo some years ago because they published cartoons they found offensive. The Muslims were so offended about being represented in a cartoon that they decided to murder people to defend their reputation, and... um.... Clearly not people thinking through things fully.
But that is the price we have to pay to maintain the far more important right to not have what we say or hear be censored. Who is smart enough to decide what YOU are allowed to hear? Personally, I've never heard of a person smart enough to decide that for me.
The liberties and freedoms we have are not meant to be abused. In an ideal world with stable people with good reasoning skill it wouldn't be a big problem. With social media more and more feral humans have access to a platform that allows like-minded folks collect. The negative that has resulted is teen suicide due to online bullying. I have been personally threatened on Facebook for sharing my views on gun laws. I stopped that completely because even if I'm not murdered in my driveway by some offended right winger the anxiety isn't worth it. Freedoms are ideals, so with ideals there has to be tolerance. But there is also a requirement to respect freedom from ourselves, but also for others. If Nazis want to march, fine. I will submit my disapproval of their racism.
