Asatro in many places has a strong negative connotation due to partially being coopted by racists. I've encountered more purported believers in Asatro who are neo-Nazi than not. They may well be a small minority for what I know, but they are vocal, and so it's a term that's tricky.
That is a form of historical appropriation that we should not just blindly accept. The word originates in the 1820s and the word as is much older. I for one will use it in its original meaning and encourage others to do as well.
I get that sentiment, though I feel it's a bit of a losing battle, because it also means you may often need to contextualize what you mean if you want to avoid misunderstandings
