Generally I find that people who say people need to be thicker skinned know themselves at what they have said, or would like to say, is beyond what normal reasonable people would find acceptable.
Just because you can say something, it doesn't mean you should.
Hopefully in this forum we will find a happy balance, where people don't take offense to easily, and the person posting will show some restraint before posting something that they know will likely cause offense to a person or group of people.
That's what debate is all about, finding a happy balance where people can actually have a meaningful discussion. If you get peoples backs up, you can expect them to get annoyed and retaliate, and at that point the debate becomes mostly irrelevant.
BTW, and for everyones information. The rules for this thread set in the above post are as much for the benefit of the members, as it is to allow the thread to be managed or the staff to put their point of view on how this forum can work.
