I'm honestly not so interested in all the matters of vulgarity in all the languages that I learn. I tend to find it way more effective to express myself precisely with appropriate words. People overusing vulgarity appear to lack either ideas (arguments) or proper vocabulary to express their thought clearly. It doesn't shock me to hear or read vulgar expressions anywhere, it's actually the opposite : it became so prominent in many places it feels quite drab and tasteless, it doesn't have any effect on me anymore.
I do find it interesting, but only in a linguistic or anthropological way.
