Yes, I literally linked to some of their history. They're all linked to right wing conspiracy groups. The founders and several of their members have posted long tirades against diversity programs, constantly retweet staunchly anti-trans people, have claimed sexually diverse (though they say perverse with no distinction about anything) nerds are the cause of all problems.

Even several of the games Collective Shout targeted specifically shows they don't actually care about truth and just want to scream louder until they get their way. They campaigned against Detroit: Become Human saying it's a vile sexist game because of a scene where you actually save a woman from being beaten by her husband, thus eliciting empathy in many players for victims of abuse (I personally remember it opening people's eyes when they played it).

They claim videogames make people violent and sexist despite mountains of evidence otherwise.

They claim Tate as their success despite many other groups actively pushing against him and his media.

Numerous LGBTQ organizations have stated how Collective Shout negatively impacts them by targeting healthy representation of being LGBTQ by calling it sexual perversion. Even Vice if I'm not mistaken ran articles diving into their negative impacts.

If you want to support truly feminist work there are plenty of valid, successful, known anti-trafficking and anti-abuse charities doing good work.
