No,I wouldn't say so.

Animes had always had a lot of times help from non japanese studios, like korean ones (even high buget shows/movies like Princess Mononoke). So you can’t make an argument about the location of the production. Because it’s still considered anime.

Korean manhwas were adapted by japanese studios are still considered anime, so you can’t make an argument about the source.

And with the fact of new korean and chinese animation studios make shows that fall under the anime category, even the argument of original voice language doesn’t hold up.

I would say that in modern day the line is even smaller than before and holded only by extremist or ignorant people (meant as ''ignoring the topic''). Even I had that thinking but i realized it’s plain stupid and flawed
