Seems like some could be just biased to their own culture too, I mean it has always been so much easier to criticize what you think as strange and non-sensical since it never had any representation in your medium before.
I don't think that really applies here; anime has been widely circulated in the West for over two decades now, it's hardly this new alien thing never before represented.
Yes, the medium(or brand) has democratisized itself a lot in the last decade (especially, since 2012-2013) amongst the younger generation and people currently at our age willing to consume medias of that form, but you'd be hard press to find it as an acutal accepted standard of our society like in TV Programs where you'd have difficulties to find something else than Toonami(Adult Swim) having a centric anime focus in it's runnning schedule.
Not mentionning that most part of our normative culture made it so that people outside of these circles will find it just as alien as it ever was.
Heck, personally I've been reading mangas since I was like 8 yo and when I still do the same today, my peers outside of my intimate circles are sure to mention how weird and strange the medium I read is.
Although, I'm not saying things haven't advance either, on the contrary, you just look at how much content the medium have seen brought in the last decade in our libraries and streaming services but I just wanna give a bit of my own perspective cuz I still think that we're far from the "All is well and good" phase here.
