So many people are so dead-set in their opinions and closed-minded that they won't let you get a word in edgewise.
Yes, I've encountered this. It is not fun. For me, debating is hard because everything I say makes sense in my head, but very rarely does it come out correctly. (This is why I like typing to people instead of actual conversation, because it comes out more accurately) And well, apparently that's actually part of my personality type, to know what I'm saying and no one else can follow. /is doomed. XD
