The issue with mansplaining is that the topic is usually, but not always a women's topic. For example men might tell women what it's like to be a woman in various situations including menstruation, attraction, sexuality, or post-male-female sexual trauma. They're not saying how women treated them, but rather WHY the women are doing certain things or even how the women feel at those times.
An example is a current thread, discussing the reasons why women don't date autistic men. In my opinion questions about why women do or don't do things should be answered by women. Men could share their experiences and of course those are valuable, but they can't answer the question without speculation because they don't know WHY.
It's even more "mansplainy" when men respond to women in threads about women, and say or suggest the women are wrong, or that they as men know more about womanhood than women respondents do. Yes, all people are different and not all women think or feel the same way on various topics pertaining to women, but women's input shouldn't be invalidated or dismissed by men who seek that input in the first place.
I can't think of comparable situations where women on WP, or in general, tell others what it's like to be a man. I doubt men would be very pleased with that if we did. Sadly, women wouldn't be called "womansplainers" if they did this. In popular culture women who do that are usually called b*****s or other derogatory terms which attack them as people, rather than identifying the specific behaviour with a verb (e.g., mansplaining).
