Am I supposed to hate certain people?
The Epistle of John is quite clear to not allow heathens into your home. There's really no way to interpret it differently, but of what "heathen" means. You either agree or snip it out. Also, in Galatians, Paul said "Let anyone who preaches a doctrine different than me be damned". As for hate itself, you must define what hate means and then ask yourself if some of the most evil people aren't undeserving of what is called "Hate".
Am I supposed to agree with slavery?
Why not? Paul says for Slaves to be obedient to their masters. You are not supposed to let the social opinions of the world affect your beliefs. Why should you let abolitionists tell you what to believe? Slavery goes on today worldwide, you don't see these liberals organizing underground railroads to help them. Many of them have probably paid for services of human trafficking before even.
Am I supposed to believe the earth is flat and only 6,000 years old?
The notion that the Bible says the Earth is flat is a demonstration of people accusing it of such of not having any clue whatsoever about the language involved. The word "Earth" always means "Land". There is no word for "Planet Earth". "Corners of the Earth" does not mean "The Earth is a Square", it is a phrase to mean "Ends of the land". The word 'Land" does not mean "Planet Earth", but it can refer to the known regions of said Earth.
As for believing the Earth is 6000 years old, that is a matter of scientific debate, I say 13,000. But this is not the science vs. religion category. It's basically a matter of whether you believe blindly with Atheist Scientific consensus and don't question their claims such as why the Earth hasn't spiraled into the sun or hit the moon by now for that matter. I say you SHOULD believe it as such if you want to conform to the beliefs of what a "Christian" in the old days would have believed before modern liberalism creeped in. There's nothing particularly scientific about the claims of an old Earth considering the RAW DATA IS NOT AVAILABLE FOR PUBLIC EXAMINATION. So if you believe it's bad for a Christian to believe that scientists are lying and hiding things, enjoy some Aspartame while you're at it. It's totally safe the scientists say. And of course their Raw data isn't available either here.
Am I supposed to judge people and tell them they are going to "hell"?
No. However, judging people is something you should ALWAYS do. If you don't judge people correctly, you could get killed or worse. What you shouldn't do is judge when you shouldn't judge. Jesus did not say "Do not judge", that's been a popular thread topic in the past. What I do believe you CAN do is say "According to the Bible, such a behavior Jesus warns leads to hellfire". But this begins a whole "Saved by grace" and "Saved by works" doctrinal debate, in which the "Saved by grace" belief tries to shuffle around, turning how Jesus clearly said that your bad behavior sends you to hell into something different about just applying to non-believers.
Am I supposed to throw stones at other faiths and such?
"Let anyone who teaches a doctrine different than me be damned". Combined with the fact that you're not supposed to let a heathen into your house even, yes, you are in fact encouraged to disparage other faiths, however, to do so truthfully, reasonably, critically, and not just things like blind Quran burnings. Instead, to be able to rationally argue against the beliefs of those who have critically opposed views.
And since I do none of those things, does that mean I am a bad Christian?
In order to define what a "bad Christian" means, you must first define what being a "Christian" means in the first place, which is another popular thread topic. By the BIBLICAL definition of Christian, virtually everyone who claims to be Christian is in fact a "bad" Christian if by "bad" you mean "one who is not aspiring to do what it says to do and is instead backpedaling or not even trying". That would include me as well.
