That is your perfect right, and very much as you say your opinion. I use swear words, and freely, but it depends. There are places I wouldn't. The people who like my writing know what to expect, and they also understand that my use of colorful language has its own purpose. That isn't true for everyone. So while I understand your point, I would also not impose my beliefs on others. Such language fits, depending on the audience, just as the use of f-bombs in comedy can be used for effect. Each to his own.
