Bernhard It is possible that you are not alone but nether are defenders of freedom if information production and distribution and in particular of freedom of speech. Trying to restrict what words people can or can not use (by labeling them sexist, racist or obscene) is the bread and butter of modern day media censorship. It is censorship and not "just political correctness". While I would not want people trying to limit contributions to Debian only to "smart and educated white people" (racism) or "logically thinking males" (sexism), going the other way and excluding people from Debian because their remarks or way of thinking might offend someone is just offensive to me. That is against the spirit of information freedom that free software is built upon.
To summarize: no one should have the power to say what you can or can not say. You personally do not have to listen to what people say if you do not like what they are saying - there are technological measures that allow you to filter people out at your end. But denying them the right to speak (or segregating them to non-Debian communication channels) is clear and simple censorship that goes against the very principles of free software.
I do not agree with what you have to say, but I'll defend to the death your right to say it.
