Alright, I know nothing about this person or the song, but I went to read the article to see where it says she is an “anti-vaxxer” and a “musk fan”, as well as “against Israel’s genocide”:

In the song, May rails against “big pharma,” a “man-made virus,” “cancel culture,” and a war that she brands “genocide.”

This is the only passage I could find that remotely hints about her stance about those things and I see the controversial “man-made virus” line, but that just means she believes the virus was man-made, e.g. it came from Wuhan’s lab, which is a hypothesis that was seriously considered, though still found less likely than the zoonotic one.

Nothing there says she’s against vaccines. It does say she’s against Israel’s genocide though, assuming that’s the war being referred here (lyrics seem to confirm that).

Searching for “vax” or “vaccine” in the entire article yields nothing.

Searching for “musk” yields this verse in the lyrics:

Mr. Musk, he said some s***, the lefts are angry

Which… doesn’t seem to imply she’s a fan either (she might be, mind you, but one can’t conclude that from this article).

So, when reading an article, let’s not extrapolate beyond what’s reasonable.

The latter, but OP appears to be a fan.
