I enjoy thinking about politics/society/controversial subjects and discussing them with the right people. Unfortunately, people tend to get butthurt pretty easily. Also, most people aren't even informed (forgivable), nor do they TRY to be informed (unforgivable) with what they're talking about.
I have yet to see a forum where people have respectful and reasoned debates about issues. It's usually just name-calling.
At the end of the day, a debate is a quest for a conclusion. It should be an experience where one is open to learning - even if it means abandoning their original ideology.
I don't think people enter the arena with that goal in mind, though. They usually just want to rave and rant.
Never could learn to drink that blood
And call it wine,
Never could learn to hold you, love,
And call you mine.
