So in the interest of fairness, and because I don't like dismissing people out of hand, I looked up the term "apex fallacy" since I'm fairly interested in critical thinking and had never heard the term.

Looking at Google, at least the first
seven references to the "apex fallacy" all reference radical feminists in their example of what the fallacy is. Several are articles about radical feminism that simply use the term. I then looked up the term in the dictionary and on wikipedia, and it is not listed.
What that tells me is that this fallacy is almost certainly a term created specifically by a group of people to arm them with jargon as needed in arguments. It suggests that people who use this term are likely people deeply invested in whatever cause created the term.
I'm not saying I know with absolute certainty that you come here in bad faith; it's impossible to know that with so little information to go on. But I would say that your language here -- not just the term "apex fallacy," but other phrases like "radfem" -- raises a lot of red flags about how objective your viewpoint is here.
