It does become a bit tiresome doesn't it? This constant need by some/many to be identified as something you obviously are through no control of your own or quite obviously aren't but feel, because you decide you are, then we all should support you in that. I have zero time for people who get offended because I don't support their protestations because they think that somehow impedes them or impacts their personal choices in life. It doesn't because you are irrelevant to me usually and you now what, I should be irrelevant to you too.
Am I proud to be white? Nope but I am also not in the slightest guilty of feel any responsibility for the nasty things some white people may have done to some 'off white' people over the years. I don't have that guilt, I don't feel I should apologise for it because it wasn't me who did it and I don't feel I owe anyone anything for it other than how I act and to acknowledge it happened and was wrong, but move on please because constant seeking of acknowledgement is pointless when acknowledged. Treat everyone the same until they give me reason not to, which is often predicated on anger when I don't support their preposterous proclamations they are for example, a martian lesbian from a star trek film because that is what they identify as. Oh right, good for you but please, really.
Live and let live but don't ask me to buy into your delusions and don't seek to impose it on me but feel free to live the life you wish. What I think or the language I use or how I discuss it with my friends should not matter to you at all, it should be irrelevant. Same as when an angry person with pink hair tells me I am 'the problem' being a white man. They are irrelevant to me, I just smile and eat some more pie.....pussy pie.
