There is something incredibly perverse and funny seeing the 
crowd appropriate left-wing activist language and slogans and applying them to their culture war talking point du jour

If you have don't have any clue what this word salad is, Sweet Baby inc is some video game story consultancy firm that gamers have decided is reaponsible for making every character gay, trans and ugly. Someone started a curated Steam collection for games they've worked on so 
s can boycott them
It makes no sense. The Mark of the Beast is supposed to be a Bad thing that Satan or the Antichrist or whomever forces people to take on
They don't even know what biblical prophecy they're yelling about
They just learned it from the weirdos who yelled at them about it and the people they learned it from didn't know what the fuck they were talking about either
The "mark of the beast" isn't a pentagram, which is a pagan symbol villainized by Christians that has no biblical backing. The mark of the beast is the number 666 placed on everyone's right hand or forehead - and everyone has to do it or they get cut out of society and exiled.
So the chuds here are taking on the role of the anti-christ if they are forcing the mark onto other subjects, and they are trying to "exile" the "woke" elements in the industry (women, trans people, queer people, non-white people) through shaming them. They much better fit the beast in this metaphor than any woke people do.
Wow, I can't believe they just ripped off the Iron Maiden song like that.
if they are applying the mark of the beast to games, that makes them the anti-christ/beast in this metaphor lmao. Not sure if they thought that one through.
