That seems to be a viewpoint that having surgery, somehow decreases the risk, or feelings of discomfort that women go through.
And whilst no penis means they can't rape you with one, I disagree in any way, that it makes them any less male.
Autogynephilia is certainly not precluded by surgery. It can be the ultimate goal, in fact.
A man who fetishises women and their biology is unwelcome on that basis, not the fact that he has a penis.
There is no framework to distinguish between a pre-op and post-op transwoman. So it's moot and pointless.
Are far more effective distinction would be to separate men with gender dysphoria from men with autogynephilia. But only in terms of the direct threat they pose. Participating unwittingly in someone's fetish is a huge boundary violation.
Men without AGP, but with gender dysphoria, don't tend to want to violate boundaries, for the sake of it.
Having said that, the presence of a male, (from either camp), certainly alters the dynamic.
Expecting women to ignore their socialisation and experience of men in general, is, in itself, a boundary violation.
A third option would be far more preferable. Segregation on the basis of sex for those who want it, and a third option for those who are gender variant.
That I would campaign for.
