"What changed? Maybe it was me, but I was also made very aware of some of the behaviour of the 'other' side in the discussion.
"Because I may have my reservations about excessive political correctness, but honestly, I absolutely do not want to be seen as being in the same camp as the low-life scum on the internet that think it's OK to be a white nationalist Nazi, and have some truly nasty misogynistic, homophobic or transphobic behaviour. And those people were complaining about too much political correctness too, and in the process just making my public stance look bad.
"And don't get me wrong, please - I'm not making excuses for some of my own rather strong language. But I do claim that it never ever was any of that kind of nastiness. I got upset with bad code, and people who made excuses for it, and used some pretty strong language in the process. Not good behaviour, but not the racist/etc claptrap some people spout.
So in the end, my 'I really don't want to be too PC' stance simply became untenable. Partly because you definitely can find some emails from me that were simply completely unacceptable, and I need to fix that going forward. But to a large degree also because I don't want to be associated with a lot of the people who complain about excessive political correctness.
