Why do you hate it?
I hate it too and can't get into it. It's one of those "faggy" communities. It tries to be quirky and has stupid error messages that try to be funny like google. I think it's a liberal thing. Conservatives would not put cheap quirky jokes in their website's functionality.
The groups actually not only downvote, but sometimes ban people who are disliked by the other members, even if no rules are broken.
Furthermore, a VERY important reason why reddit is garbage is this: Online debates are interesting BECAUSE people can freely disagree and play devil's advocate. Reddit destroys this. It's complete and utter garbage.
