Yes. You appear to disagree.
Whom do you think should decide who can say what, and to whom?
While certain language can be deemed unseemly, and usually counterproductive, it seems to me that society should be the culture police, with society deciding (albeit without legal recourse) that certain activities in the public square are deemed beneath us and subject to derision, and thus the purveyors of such are treated accordingly, by being ignored.
Now, one might think that this has the potential to expose us to bad ideas, and I hope it does, as I’d much prefer bad ideas, “bad words,” and their possible corruption of others be as open as possible, wouldn’t you? After all, how does society respond unless it’s open enough to know it, see it and hear it TO decry it?
