This is exactly what women's organisations should be doing but aren't.
Well, some women's organisations aren't. I work for a women's organisation and we always quote the EA 2010 exemption in our recruitment ads (we are so 20th Century - not a bit woke...or even scared, really).
I'm actually impressed by that recruitment advert because it does acknowledge the sex class male/men as perpetrators of DV. (But I don't believe perpetrator programmes actually do much to help women and children. In my experience, perpetrator programmes just give men new tools and language to use in their abuse but maybe that's another thread...)
I agree though - we shouldn't take the piss where male sex specific services are warranted because doing that will only turn round and bite female sex specific services on the bum at some point.
Might be handy to screenshot the jobad for evidence that male people also might benefit from same sex provision though...
