Slowly but surely AmiMojo is tempering and starting to make a little more sense in those regards. Don't ruin it! They have some valid things to say. Just point out logical inconsistencies and don't expect a reply. If you watch, over a period of six months or so, they've tempered their responses quite a bit and seem to be relying more on facts than before. Another few years and they'll see the people they're willingly associating with, perhaps retain the views, and be willing to actually have a logical discussion. These things take time! :D (There's nothing intrinsically wrong with having empathy.)
Seconded. I've (very politely) been pointing out the lack of evidence every time I see evidence-less claim from the usual crowd; once you take the usual soundbites out of the discussion by pointing out that they are not valid assumptions then any normal person would repeat it less often. For example,
The argument that there were more female coders in the 80's/eastern countries, hence it must be misogyny that keeps them out? Well, in the 80's/eastern countries women had/have fewer choices. Females in tech is inversely correlated with the number of options they have.
Male privilege? White women are by far and away the most well-off demographic in the world by every measurable standard of living metric.
Brain differences? Depending on what is being claimed, you'll either see "there is no difference" or "there are physiological differences", often both from the same person (AmiMoJo makes both claims, often in the same thread).
It takes a very stupid person indeed to repeat a debunked claim.
