yeah - you’re right. Assault is definitely OK, rather than waiting 3 minutes for the guy/girl to leave.
Just like - if I see a car parked in handicapped, but doesn’t have a sticker, I should key it, and slash the tires.
And if someone cuts in front of me in line - I should just kill them.
Or maybe - just poison the dogs who defecate on my lawn.
I think you get the idea.
You are treating morally disparate things as if they were morally equivalent. Sexual deviants need to be kept out of women’s restrooms. Sometimes the lesson has to be emphatic. Too bad if it offends your tender sensibilities...or perhaps you think it doesn’t matter because black women use the restroom.
