Yep, but that poster also said "Glad he didn't get away with it" immediately following the sentence you quoted. Which, to me, means they're saying his misogyny is also relevant to his spat with Arlene Foster. I was simply saying otherwise.
I can't comment on who he didn't target, but he targeted her because of a rumour about her, which I obviously won't repeat here.
My point is that all homophobia is bad regardless of the gender of the person who espouses such views. Trying to make this solely about Arlene's gender, while ignoring her homophobia, is disappointing.
As is all misogyny.
