A guy who was vaguely connected to my social circle once made a “joke” that the best way to shut up a politically opinionated woman was to force your cock into her mouth. I refused to ever meet up with him again because he advocated sexual violence. And some dudes in the group said “aww it was a joke ! He wouldn’t really do that!” But then someone actually started arguing, in his defence , that there was no sexual threat or violent implication in what he said. Men are so soaked in sexually violent rhetoric they don’t even recognise it. It doesn’t surprise me these people went to all the trouble of making a giant banner at a public event saying “suck my dick”… it comes naturally to them.
They recognize it. They just don’t like that you did and are gaslighting you.
Nothing more male than viewing sex as a weapon.
