Well it seems a bit obvious to me. I don't hate you, but I think I can guess.
Some clues: We are on a forum.
This gets rid of racism, sexism, and any other thing like that unless you have told people information about you.
The number one thing we do on a forum is make posts (and read them)
How you write, and what you write about will greatly influence people's opinions about you.
Your signature gives a hint, it appears you know some of the answer already.
I could go into more detail, but I think this is enough to make an intelligent guess. People consider a lot your posts obnoxious, irrelevant, not helpful, and/or poorly composed.
To remedy this, I would consider not creating any new topics for a while, posting in sensible, coherent sentences, and making sure that anything you post is relevant to the topic, helpful, and not mean.
Overall, I didn't even get much of a sense that people felt like they hated you, but if you think you have noticed this, I would strongly suggest considering my advise and doing your best to be a sensible, mature person.
I could be completely wrong, but that's my best guess. If you have any more questions, you may ask me until/(if) this thread is deleted or locked, and than you can PM me if you are still confused on how to act on a forums.
