So, what's the line of what you'd say is "acceptable scientific belief" and "you're ****ing nuts"? Because we are seeing more and more biological men getting menstrual cramps and doing shit like this...
Biological male: "I'm going to be a mother!"

And the problem isn't at all that these people exist. Good for them. Have at it.
The problem arises that they build up followings that are incredible gullible...and then aggressive in espousing this stuff to the point of calling people "ignorant bigots" for "ignoring the science" that they've made up out of thin air. This is the crux of the issue, IMO. You find yourself in the wrong room and say "Men can't lactate" and before you know it, you're suspended from your job for insensitivity.
