I guess you really must be new here, newhere24. Nonetheless it doesn't seem to have dented your confidence to supply us with "facts".
"Fact" 1 is curious! You thought feminists coined the term TERF? It would be most unusual if true (it's not, obvs). Perhaps you were unaware that disadvantaged groups do sometimes reclaim slurs, but quite obviously that differs vastly from the slur being used against the group, with the same malicious intent with which the slur was coined.
Feminists did coin PERF as a more accurate acronym. P standing for Penis. Perhaps that's what confused you instead.
"Fact" 2 the transwoman was being criticised not for being trans, but for using a slur created with the purpose of othering feminist women, thus legitimising the violent threats and silencing they receive. See my response to "fact" one. There are plenty of reclaimed slurs that are certainly not ok if used, you know, as a slur. Trans may be a minority group, much like other belief systems, but the power differentials in the world of dating are always stacked in the male's favour, whatever they believe in.
"Fact" 3. Personally I admire people who call out genuine bigotry as OP did. But I take on board the suggestion that dating sites aren't the place. Of course, dating sites aren't the place for misogynist slurs either.
