This feminist, who goes by “House Mouse Queen of Doom”, articulates the circularity of Bill C-16 and why it means the end of sisterhood. I urge you to read the whole thing. Here’s some excerpts:

Internal experiences and sensations are not material realities and cannot be legislated. Gender resides in your psychology. It’s interesting they use the term ‘sense.’ We can’t legislate senses because they are highly inaccurate. Also if ‘there are a variety’ of individual experiences of gender, which ones matter?

In fact, because gender identity relies on ‘sense’, all a male has to do is claim he’s a woman and he’ll be allowed into any women’s space he wants. Women’s shelters, prisons, organizations, sports teams, events, etc. are now all open any male who ‘senses’ he’s a woman.

Say goodbye to women-only spaces. Say goodbye to privacy. Say goodbye to women’s sports. Say goodbye to safety. Say goodbye to your class protections.

Men want in.

Say goodbye to sisterhood.
