in reply to Politeness (to one another) is a virtue
I am profoundly offended by these comments.
To quote John Cleese: you don't have the right to not be offended.
Seriously, if you feel offended by the things you quote, I think you need professional help. And I seriously recommend you to do away with all computers, and when you read the newspaper, to skip the "letters to the editor" section.
None of the things you quote is directed to you -- or even directed to anyone or any specific group. Anyone who feels offended and doesn't want to feel offended by it should look at himself, instead of being dramatic on a public forum.
