One of the strange psychological effects of multiculturalism as a doctrine or ideology is that it renders people peculiarly uninterested in or insensitive to the ideas or feelings of people of cultures other than their own…  If we must respect others, others must respect us. And if our ‘culture’ happens to include [offensive behavior], others must just grin and bear it, otherwise they are being retrograde, primitive and (worst of all) intolerant.
