Everyone hates each other.
People don't respect the rules/Rules aren't being enforced.
...people freak out and complain when people complain...
This witch hunt against unvalidated users...
Honestly I really don't see why these things even need to be pointed out. Literally and I don't believe I'm exaggerating here, literally every forum out there for just about anything, that still has a active/somewhat active community, has these problems, if you can even call them that, I mean they appear so often that you can just as well call them a trait of an internet forum, or insert them in the definition of an internet forum, I dunno call it: "A place on the internet where people gather to bicker about everything and where everyone thinks they are right."
We all have these moments when we suffer these symptoms of a let's call it "forum sickness" or "internet-forumitis". Symptoms include: The Subjects become sanctimonious, aggressive and very defensive of their ideas at the same time extremely sensitive, like a bomb that waits to explode once you push the wrong button, hateful towards those who disapproves those ideas, and probably some other symptoms that I missed. Even when one thinks he is better than all those things mentioned and unmentioned, there will be something that will just prove him wrong.
I honestly hope this hasn't been posted in some hope that such things may somehow be solved because they cannot, I repeat cannot be solved. I'll even take the liberty to analyze each of the problems pointed out.
Everyone hates each other: Happens everywhere and it depends on the human nature itself therefore it cannot be cured. Status: Pandemic disease. Cure: None(Unless you count purging every single member on a forum)
People don't respect the rules/Rules aren't being enforced: Happens everywhere, there will always be people like these who break the rules, as for the enforcement problems, well even if the law is being properly enforced the problem will still persist no matter what. Also if laws are enforced too strictly the result is a barren and boring lackluster forum. Status: Pandemic disease. Cure: Partial, must be administered very carefully and as regularly as possible if need be.
...people freak out and complain when people complain...: Happens everywhere and it depends on the human nature itself therefore it cannot be cured. Status: Pandemic disease.

This witch hunt against unvalidated users...: Happens occasionally and it comes in many shapes and forms, it also depends mostly on human nature. Status: Similar to a seasonal disease it appears on certain occasions, or for certain reasons, but unlike one it can last indefinitely. Cure: Varies from disease to disease. It could be cured if the cause of the disease would somehow be changed or removed.
All these small diseases form the big one "internet-forumitis". Now I may know nothing about how a real disease really works but I know for sure, having been on plenty of other forums that this is exactly the way this particular disease works on every single one of them.
Now look there are actually 3 things one can do to deal with this big disease:
1. Go on with his affairs and try to ignore it.
2. Stay silent and choose only to watch so that he doesn't somehow contribute to the problem
3. Quit the forum.
