The bias is that: how do you handle the fact that any man could claim to be a woman and be housed with women? Especially when the issue is compounded by those numbers on rape they're reporting? Do you build special quarters in every prison? For the 47 individuals in 50~70k detainees? Be realistic and have a more balanced view of the matter.
I think the "bias blindness" of WP is a weapon selectively applied to one side and should be removed in favour of sources that at least pretend neutrality. The problem is obviously that you almost have no source left, then; at least in the political/ideological domain.
