Generation Gap

Something that irritates me is the process of old thinking that happens with most adults over the age of 30. For some reason, they're stuck in the mindset of "negative, negative, negative." If there's something that they feel very strongly about, anything opposing it is seen as false, trite, or even evil in their eyes. It's frustrating to me, as a moderately liberal thinker and an open minded individual. I'm not capable of having a decent conversation with someone who's of this mindset without getting into a heated argument where at some point the other party just ends up getting pissed off! I don't even understand how it can be such a one way street with some people. So black and white that any sort of gray is unthinkable. What a time we live in...
