Please don’t argue with people who are either not here or have not expressed any opinion yet. You are literally strawmanning. Argue with actual people and their actual opinions instead of made-up stereotypes.

Who are you quoting? Are they here? No? Then stop arguing with them here.

who, how or why does it matter if that was the concept or is just a side effect?

because intention defines how to judge an action. if somebody moves a knife into your body, then it can be a violent attack or a medical procedure. if you devide boys and girls into groups then it can be seen as sexism or a as a mindful act to ensure privacy and intimacy.

it's the same here. these men just want to be alone.
