This is absolutely something that was and is done by older lgbtq+ people and flamboyant people during protests and marches to normalize the fact that men can have breasts, that men can look like anything and still be men.
It reminds me of how trumeds like to claim that the community founders would have hated people like me, but trumeds are the ones who would have hated the community founders. The people who started the protests, the people who were “too” flamboyant, too loud, too non-conforming, the people who put themselves in the line of fire for harassment and hate, etc.
