The fundamental issue here is that you think we're the problem for calling you out on some "accidental" sentiment you displayed a while ago.
The real problem is you. People use your history against you because, in acting like a cunt, you remind them of the bad things you've done. The only way to move forward and not have your past haunt you is to act like a new person. Just today you tried to belittle me, and so people were quite happy to rush in and remind you that you're way, way below the pedestal.
You have to change yourself to change the opinions about you. If you, from this point forward, only post positive messages and contribute in a way that people like, nobody is going to bring your stuff up. Hell, maybe they'll forget after long. But it's not going to start until you stop.
