I dont think its fair to say that Social media sites banning the sex industry is a move that stems from hostility. Its just our culture that we separate sex and normal life. Maybe for children, maybe for ourselves. I dont want my timeline on fb to fill up with ads for porn creators. When i do want to consume porn i know where to go.
But, that’s not the way most social media approaches the problem. Given that there are alternate ways to address the problem that aren’t being tried, I don’t see “hostility” as an unreasonable take.
