I have opined many times that I believe there is no such thing as bad language, or strong language, there is simply language.
The important aspect of being an adult is learning what language is appropriate where, and when, and using it accordingly.
I worked with telephone engineers for over forty years, and heard often, and occasionally used, language that would make a stevedore blush, but I never use it when speaking to my wife and children, or they with me, because politeness is respect.
I agree swearing is a good release - all swear words have harsh consonents, so they can be accented with vigour when used, but I repeat, the time and place of that use is a matter for consideration of the recipient, and people within earshot.
