When I moved to Canada in 1970, guys wouldn’t curse around women. When I moved back to the States a decade later, the change in culture was a shock.
Not only did guys curse around girls, but girls had the dirtiest mouths of the two. Tattoos, piercing, and earrings were everywhere.
But the dogs bark and the caravan moves on. What is filth to you is standard fare among those not much younger than us. I’m glad cable TV is relatively uncensored, for the sake of believability.
By all means, you fill your mind with all the filth you want. It apparently agrees with you.
