Well... I guess a lot of people don't see the Net as predominantly American one way or another.
The bottom line is that you have to expect that people will disagree with you and that, from time to time, they'll express themselves in a way that, though not necessarily calculated to give offense, nevertheless does.
It's difficult to put up with someone who expresses ideas and opinions that you may not agree with, or that you find repugnant, but sometimes we have to. I may not agree with what you say, but I'll defend your right to say it.
