Yes, but pride in an identity that has been marginalised - and seeking to reclaim how that identity is expressed by appropriating some of the vocabulary of the oppressors - is one thing.
Pride in opinions, and views (views which were once expressed as deeply offensive and unfair and oppressive laws, whereby women, blacks and gays were deprived of, or denied, rights, simply by virtue of who and what they were) which seek to express such abhorrent attitudes is quite another.
I fully take the point that anyone who chooses to have a racist, sexist, or homophobic avatar identifies themselves is choosing to advertise the fact that their views are repellant.
I agree with the notion that these attitudes are abhorrent and was simply speaking to their motivations. I don't think the desire, when uploading inane avatars, is to offend, which isn't to say that the uploader is unaware of how offensive their image is.
