You really can't hate a language (well, I do have a complex relationship with PHP). What people hate are stereotypes built around communities. Usually from the conduct of some individuals. Every community has them. I mean, even the COBOL guys must roll their eyes anytime someone writes some douche comment about the language.

Don't pay attention to them. There are many nice people in the Ruby community. People who are there for the code, and not the drama.

Now, don't get me started about those Visual Basic guys... :)
