What's something you once had a lot of respect for but now have no respect for?

I would have to say organized religion. I grew up in a pretty strict christian home, but as I grew older I began to see how much of what I had been told was just patently false and designed to manipulate and control. I have done a lot (decades worth) of studying and reading and I'm confident that the conclusions I have arrived at are correct. Of course, your mileage may vary.
