Ehm, no? Nobody gives a shit if you speak your region's language as long as you don't want to use it as an excuse to secede. Think of Galicians, Asturians and Valencians
Catalan and euskera are somehow secesionist languages? That’s exactly what I was talking about. By the way, valencian and catalan are the same language. https://en.m.wikipedia.org/wiki/Valencian_language
Tell that to a Valencian and they'll rip your head off like if you just made a "paella"
And no, they aren't "separatist languages", but secessionists use them as a symbol of their goals like if a country couldn't have co-official languages
