I think that if things can be discussed in a manner that is not purposely designed to give offense, then why can we not have adult conversations about things? How can we learn about things if we don't discuss them?
If you don't want to learn about some things, then don't read the arguments for and against....
Personally, I feel I am quite open-minded, but am always willing to learn more about things I know little about. The only exception I make to anything is if someone is trying to force an opinion upon me.
