A great thread! I've read each and every post in this fascinating thread with great interest. Finally, I have the time to write up some of my own thoughts.
Yes, I've definitely changed over the years. I've always been a very emperical, data driven person so changing my beliefs to fit the latest data has never been a problem. I tend not to latch on to beliefs as being inherently correct so it makes changing them as needed easier.
As I've grown older I've noticed that I see far fewer issues as black or white. Almost everything is a shade of gray. You can't put most of the real world into neat little boxes. In the same vein, I don't try to label people and put them in these little boxes. People are people and you should judge them in their entirety, but mostly on kindness, caring, etc.
Like many have mentioned, I used to think homosexuals were icky up to around high school. However, that has long gone by the wayside and I think equal rights for everything (including marriage) is required. Again, they are just people who want to live a happy life. Why make it tougher?
My attitudes towards people have become both more open and more narrow. I'm happy socializing with many more types of people. I LOVE
women and, similarly, can be attracted and care about many more types than before. However, I've also become more closed off to certain types. Anyone who is self-absorbed, uncaring, etc., I just don't have the time of day. Life is too short, which becomes all the more clear as you grow older. Also, anyone who is, well stupid and consistently making bad choices, into the drama, etc, again, I just don't have the time for.
I guess the most surprising change for me relates to spirituality. As I said, I'm very emperical and was always an extreme skeptic. Now, I still don't believe in any good or even spirituality. I haven't gone that far. But, I'm willing to believe that there could be more. And, that's more based on the truly extreme weirdness of the universe that we're just barely scratching the surface of. That doesn't mean there is a creator or some other basis for spiritualism, just that I no longer dismiss it out of hand! For me, a huge step!
