That is why the Bavarian law which states that "teachers' attire must be in line with 'western Christian' values" is perfectly proper and in fact necessary. By wearing a head scarf, a Muslim woman is proclaiming that we are all slaves. And that is an act that cannot be allowed or tolerated, since it brazenly attacks the central idea that is constitutive of European civilization (I won't say "Western civilization", since the anglophone world seems to have given up on it), and thus expresses a desire to destroy that civilization.

Wearing a headscarf is 'proclaiming that we're all slaves' ... 'express[ing] a desire to destroy [European] civilization'.  Ummh, don't you think this is just a wee bit over the top?
