I do swear, and many I know do as well.
I don’t, however, like people that swear all the time. It butchers the language and makes one seem like an uncultured peasant. Swearing from time to time, like when one is angry, is ok, but if every second word of yours is “fuck”, you need to read a book, dude.
My swearing usually consists of a few curse words, but I am not creative in cursing and I don’t do it all the time. I am actually kind of disgusted upon hearing someone swearing like a sailor.
