It’s also ridiculous that they suggest that people are influenced by social pressure or even marketing to become trans. Not only does this not happen, if it did happen it would not work. Conversion therapy does not work. You can’t make people trans just like you can’t make people cis. If people who are actually cis transition they get gender dysphoria and become miserable.
This is just conservative fearmongering with no basis in reality.
The Steam Deck is just a Linux PC, you can absolutely mod games on it!
I’m playing modded Slay the Spire a lot on mine.
