@FBM,
Hmmm...
I am here for interesting discussion. That is why the personal attacks are what really cross the line for me. They make it very difficult to make logical points or to reach understanding. Every slightly controversial post devolves into a mud slinging contest (the facts back on this). It would be very nice for me to have a reasoned discussion with people I disagree with. This is nearly impossible because the ever escalating name-calling drowns it out.
I disagree with your point about eliciting a strongly negative response. Isn't this a prescription for group think.
In a public forum, people will strongly disagree. Ideally people could strongly disagree in a respectful way. I enjoy sharing ideas with people I disagree with. I want to hear their arguments. Sometimes I learn from them.
I have a negative response to something someone says... how is this their responsibility? In a public forum, they are going to express their opinions.
If posters in a public forum have to censor sincerely held beliefs because other posters might respond negatively... how is reasoned discussion possible?
Are you saying that no one should express an opinion that might offend you?
