Don't let them bluepill you. I agree that masturbating about what went wrong in your life is not ok but you need to be realist. Because with their positivity coping mechanism all you're going to do is just illude yourself. You're 20 years old and never had a girlfriend,nor seem to have a normal social life,and that has nothing to do with sluthate nor with being negative,because i doubt you're 24/7 being a piece of shit to people,and you even said people betrayed your kindness. Everything that wrent wrong with your life can't be adressed to a web forum. Sluthate is not some kind of sorcery which magically transforms your life in shit. The truth is your life was already shit to begin,you just found out a website with people who share the same experiences,who,coincidence,are below average in the looks spectrum,who indeed may even be awkward but that is none of their fault,if they would have been bombarded with positive social feedback like goodlooking persons,they would not have social anxiety or similar things. That's what makes you mad or bitter,not the website per se,because if you were some normal dude with a relative happy life,you would just not care about what its said in the forum because you never experienced such thing.
The thing is halo effect is indeed real,you may have been misthreated just because of your looks,that's how fucked up the thing is.

It really is just a hysteria towards sluthate because they prefer to blame the website instead of adressing that the real problem is how looks dictate 99% of how people see us.
