The mission of this sub:

"Our mission is to provide a place where all women can comfortably and candidly present their viewpoints for community discussion in a non-judgmental space." (emphasis mine.)

Behaviors specifically prohibited in the rules:

No pot-stirring. No agenda questions. This is not your personal soapbox. No derailing. Talk via PM or start a new thread. No invalidation.

While men can still offer input, if your view conflicts with a woman's, we ask that you do not downvote or invalidate her response. (emphasis mine)

Now, if you come in, as a man, to a space where the mission is explicitly provide a space for women to feel comfortable sharing their opinion in a non-judgmental environment, where pot-stirring, agenda, derailing, and invalidating are all prohibited behaviors, and you say something like, "b-b-but isn't arguing what a thread-based forum is FOR," isn't that imposing your own definition of what something is for and what YOU are familiar and comfortable doing with it, on a space that's not for you?
