No one has called out rpietila for the 'raghead' comment, so I will. Add racist to the list of faults.
You see how little support PC actually has.

It is one of the many repression techniques forced on us, completely unfounded in logic and not supported by conscience.

It's easy to see cultural insensitivity as a non-problem (and complaints about it as illogical) if you're lucky enough to be in a cultural group that isn't typically on the receiving end of such insensitivity. Failing to perceive the problem doesn't make the problem go away, though.
