This author mixes together statements and examples of racism, culturalism and religious intolerance as if they are the same thing and are interchangeable.  They are not.  I can deplore certain cultural practices and religious beliefs without ever going near the scourge of racism.

For example, I'm not keen to get to know or be pals with someone whose foundational religious beliefs call for me to be hunted down and exterminated.  I don't care about the colour of their skin or wence they came or their ethnic background but I find that religious belief to be more than somewhat repugnant and intolerable.
