Seen this on reddit and thought it was an interesting question that largely is not talked about.
It is largely an issue that gets sidelined and hidden because people don’t want to talk about it or accept that it exists. Hopefully this gets some traction to break that marginalisation.
This may be a boring answer but I don’t deal with it simply because I’m not drawn to online spaces where it occurs. I don’t know what I would do if I did experience misandry. Leave? Engaging probably wouldn’t help.
