i've never heard him speak or seen anything except photos and commentary on him but he is presumably a massive prick.
this is really where cultural change is happening now though, through these kinds of personalities and their output. for a while musicians were playing a paralell role to his, which is to say giving lads some kind of model and philosophy to emulate, particuarly in terms of making sense of how to think about sex and women. the rolling stones led zeppelin and the 70s rock thing are the easy example, people always seemed to look up to them, the hedonistic thing of which girls were a main component, but you could make the same case more recently for dre and the g-funk lads and the bitches and hoes thing. or i don't know, boyzone, which is a more wholesome formulation of it.
forgetting the girls thing and speaking more broadly hardly anyone is forming their identities around some equivelent of the manic street preachers or fugazi or whatever. loads of people of all ages are forming thier identities and worldview around andrew tate, charlie di melio, jordan peterson, that geezer who did those daily videos drably explaining the pandemic, the red scare girls, whatever. arguably k punk played this role to a niche of people (like me) as well, an early example of that for the early adopters of this mode of thing
at the same time pop(ular) music seems to get more intimate, more direct, less mysterious and more confessional
