Yes, I would imagine that the people watching are not particular impressed at a poster on a Feminism board wilfully erasing and belittling women's experiences, and then doubling down on that position when called on it.
I know what's being done here. It's called a logical fallacy. Taking the outliers, the women who DO have to dilate, as being representative of women as a whole.
Bottom line is that generally, vaginas don't need to be dilated EVER. Just because a few women, relatively speaking, have to dilate doesn't mean that MEN have vaginas or that they can get one from a surgeon.
Vaginas are specific organs that have a whole structure and function that can NOT be created in a biological male. Men can think that's what they're getting all day, they can bleat all day about it but they DO NOT have a vagina. They have a surgically constructed wound that ALWAYS wants to heal.
Vaginas don't do this.
