"It irks me to have these misguided PC pricks constantly dictate what is offensive and what is not."

We do not dictate, we simply say how feel.

Clearly you make an important point about how people choose to name themselves and why we should respect that. But we have a long history in Western Europe, North America and so on, of treating a number of groups very badly. It has been not uncommon for "white" people to mock and descriminate against "black" people. That is why we are offended by "white" people blacking up for reasons that are often unclear. Our comments here are a very small event, much smaller than people blacking up for what I think is called fun and entertaniment.

What ever reasons you have for supporting these events it is difficult to see the relevance of calling us "pseudo-PC middle-class, middle-England white bleeding heart bollocks." Especially since you have no real idea of who we are.
