Why is there such a large amount of communist and transgender related posts on the Fediverse compared to other platforms? - Lemmy.world

I am not criticizing them, I’m just out of the loop.

Trans people and communists are nearly half of software dev. The other half are furries.
They’re 90% of FOSS development. Also, their “daily driver” is an old thinkpad running linux – often Arch.
I use Arch btw
