Yeah, there was another huge blow-up online yesterday. It happens. And yet again it was caused by someone who is a former member of SFWA. Please bear that in mind.
These online embarrassments are not an indication that people should leave / not join SFWA. Nor, except in the minds of controversy-obsessed journalists, are they evidence that science fiction and fantasy are still a boys-only club. What they are is evidence that SFWA, and the SF&F community, are changing, and that the conservatives are unhappy about it.
That’s not something to be embarrassed about, it is something to celebrate.
