Fash? They're not fash but a vegan straight edge band that makes a ton of their songs around apocalyptic scenarios based on animal product and drug consumption.
There was a subsect of straight edge vegans called Hardline, which is very troubling, but they have denied association with Hardline subculture.
They're certainly not the most based band ever, but they're not too explicitly convicted in talking about anything besides veganism and straight edge lifestyle. They have also denounced white supremacy.
My biggest concern is that some members have expressed anti-abortion views in an effort to pitifully tie it to their veganism, but I still dig the band otherwise.
Their best-known song Firestorm is basically a fantasy about killing criminals, which is pretty chuddy in my opinion. Plus, it has these lyrics:
A chemically tainted welfare generation
Absolute complete moral d****ration
So not great
In general, they use the D-word a lot in their songs, as well as references to Sodom and Gomorrah which to me is pretty sus, it may not be overtly fascist but definitely in that same puritan ballpark. They also reference anti-abortion stuff as you mentioned, mention the second amendment, demonize drug addicts, do some anti-communism etc.
The best way I could really describe their views would be incoherent and that's putting it mildly. They have all that suspect stuff but also a song about the genocide of indigenous people as well as all the animal liberation and veganism stuff, which of course is and the only thing I'll unreservedly give them credit for.
