You've said the same thing like 10 times already and each time, you make the wrong conclusion. Why does the thread on God's existance get 5+ pages of responses, and a thread on the british electoral system get 0? Do we love to hate God?
People view and respond to threads that they have opinions and background knowledge on. Due to Ja Rule's popularity and increased non-popularity(Due to 50 Cent, you could say), it only makes sense that a large amount of people will wish to know what's going on with Ja Rule. I'd answer your question on why people love to hate if it didn't derive from this Ja rule and thread popularity shit.
