If a transwoman passes, they get to experience half of one facet of what being a woman is. They get to know what it's like for people to react to you as a woman.
Say a passing transwoman is catcalled. We all know what Paris Lees thinks about catcalling.
But the transwoman doesn't have the knowledge that they have female biology, they have a different worry, their male biology and the danger from violent men who may harm them if they find out about it. On top of this they don't have female socialisation to minimise, not overreact, not react at all.
There is no way for a man to experience any other facet of womanhood.
So when a man declares themselves a woman and makes absolutely no effort to pass, quite the opposite, Danielle is holding on to every last scrap of male privilege. It's the same as non-binary people. They make zero permanent changes to their lives - maybe a name change or insisting on pronouns, changes they can easily shed - but claim to have 'literally zero rights' and to be oppressed.
Perhaps Danielle is a radfem invention to hurry along peak trans? I don't know how anyone can go along with it, he's a gift really.
