"The question of whether it is possible for everyone is hurting the myth of "everyone can do everything" on which the western societies are built in a more or less large part."
You of course have to sneak in such a broad generalization to answer the question. That making you feel superior is not so different from some of the men on the women's chess threads feeling superior to all women (even the ones with higher ratings than them) because men on average are better players. You could simply focus on saying things that directly address the question.
Mind you, I'm only talking about some people. Kingpatzer has made some great posts, especially #656.
