Your experience is interesting. I find that while I have started looking on more things as more insane than before, it has made me less argumentative and more tolerant. My thought process is something like, "So many people are so wrong on so much stuff that my trying to help them usually won't make a difference. They never had a chance to become right because they were exposed to all the wrong memes. So I'll stop trying to improve other people's thinking except where I think it might actually work, and then I'll be nice so that I don't lose a rare chance to help somebody." The eventual effect is that I see more of the irrationality around me, but feel less need to do anything about it.

I don't know if trying to emulate my reaction sounds like something you'd want, and I'm even less confident that it will work, but I find that just seeing how other people deal with something can give me ideas about how I should do so.
