It depends on how severe it is, and in that case, I’d ignore it but not like it. However, a lot of people would love to make fun of such a person, assuming they were in an area where “wiggers” were outnumbered.
I think a big problem with those sorts of people – and I’m sure many Blacks agree – is that you can be White, act Black and then revert to being White. However, you cannot be Black, act Black and then become White – lol. Being Black and acting Black is a one-way street.
How do Blacks feel about this? It’s a good guess that they don’t like it too much!
