It's a class thing. GL is too loud, too unkempt, too vernacular in speech, too Irish, too working/lower middle class.
The posh 'male feminists' (eurgghh) who speak of him with disgust-tinged pity do so because they want to keep their place in the elites club and are terrified of falling foul of woke warriors.
They lose, because GL is a one in a generation comedic talent who wrote a show that has entered the cultural lexicon in the great British & Irish comic traditions.
He's also honest, brave and intellectually courageous enough to speak out about an era-defining attack on women.
Nish Kumar, by contrast, hasn't, isn't and won't.
