I own a few of these.

Antifa is the lowest rung of humanity and few things make them seethe harder than real metal, hence their many attempts to infiltrate and claim it by way of adjacent genre crossover. Reminder that before they became useful globohomo soldiers in the trump era and got their USAID cash injections, antifa were mostly meddlers who attempted to get music gigs cancelled for European bands whom they deemed to be insufficiently communist. It's what they default to whenever they have nothing better to do (or be paid to do). Here is a deleted antifa blog boasting about attempts to screw with a Marduk gig in Texas in 2017. Marduk is completely middle of the road and isn't even in the video guy's list.

Most of the complaints listed in the vid are old, old cancel attempts. One example, the Leviathan/Sapthuran split: the guy behind Leviathan faced domestic battery charges because he threw some tattoo ink implements at the BPD bitch he was dating at the time. This transformed online into 'HE RAPED A WOMAN WITH A TATTOO GUN' and lefty feminist retards spammed all Leviathan pages with bullshit like that for years.

He's wrong about that split album btw, it has one of the very best Leviathan tracks - arguably one of the best BM tracks ever - on it.
