I'm just repeating the same thing, and really have nothing left to add.
People draw red lines all the time in terms of when "debate" is not seen as socially acceptable; where it's not acceptable to respect the other person's opinion. It's generally not acceptable to respect other people's opinions on racism. We all have to agree that racism is bad. On this site, if you say anything deviating from support from Ukraine, that is not acceptable. The list goes on into infinity.
Many women - the majority of them - think that being able to decide what they do with their own bodies qualifies as a red line, and that being civil about the opposite opinion (actually, we'll tell you what to do with your body) is ridiculous and insane. In addition to that being one of their red lines, to then bring that up in the context of a cat birthday cake just further emphasizes that the whole thing is considered trivial, and unimportant - which probably makes them angry. And this is after PS publicly took political stances on other issues.
You clearly disagree with me, so whatever. I've said what I have to say on it already.
