I'm a native English speaker and I've noticed that swearing no longer feels like a big deal. Our media and online discourse are saturated with the worst swears our language has to bear, to the point none of it hits with gravity.
I also think some of it has to do with changing generational attitudes. Millennials and Gen Z use swearing as friendly banter. You can call your casual friend a "fucking asshole", and as long as you're smiling and laughing, it's an endearing gesture. And if it were truly meant as a jab, it doesn't even sting.
The only words you can't (and shouldn't!) say are racial epithets. Those are untouchable. It's almost like what swear words themselves felt like when I was a child and knew I would be punished for saying "shit" or "damn".
