It's not just in Open Source Software that SJWs are actively looking to discredit and disemploy individuals they have targeted. I received this just yesterday.
Someone needs to get that man a copy of SJWAL, stat! And be sure that you provide anyone you know to be under attack with a link to The SJW Attack Survival Guide (PDF).SJWs are attempting to railroad another STEM figure out of his job. I can't divulge how I know this, but I have direct inside information. One individual in particular is gathering support by digging for information and asking for legal advice. They are attempting to circumvent the statute of limitations so they can deprive this man of his job.
This is happening, because of the easy success SJWs had ousting Tim Hunt and Geoff Marcy. One SJW actually said, "Now that we've brought down one of the biggest men in science, who can we go after next?" They're LOOKING for people to go after. It's just as you said. Every time one of these men apologizes, it just emboldens the SJWs.
Note that apologizing not only make it worse for the target apologizing, but for the subsequent targets as well.
Do not apologize. Never apologize. Don't even let the merest glimmer of the notion think about crossing your mind. Own your actions, own your words, and stand by them under fire.
