I think is the one thing that people who negatively perceive challenges to their worldview can't get their head around. You can get so used to having others just politely accept/not care about your opinions, that it's a shock to the system almost. You're not used to having to re-evaluate your views. Then you come up against the roadblock: forming a grounded and informed opinion and/or argument that you can eloquently communicate is hard. It takes, among other things, time, education, open-mindedness, work, constant revision, and commitment. Some just can't get over that wall. Which is a shame when you have people who can make an argument as well as kleinbl00. It's only in the last month or so that I've grown to truly appreciate that. For my masters we're given a paper week which we then have to come in and discuss and critique for a 2 hour session. The professor heads the session, but we're expected to a majority of discussion amongst ourselves. Those are intense sessions. You think you have a grip, then the professor throws in some crazy theoretical knowledge or applies something seemingly unrelated to completely change the playing field. It's impressive and inspiring. They're fast becoming my favourite.Me challenging your ideas delivers you a fuckload more benefits than it does me.
