I always find it funny that "free speech" advocates are often so interested in promoting a single kind of speech all the while ignoring the thousands of other areas of speech where we are far, far freer than we ever were. Oh, noes. We can't have a setting that features slavery as a central element, but, heaven forbid that we have two men living together in a module. Fifty years and we have exactly one matriarchy in the Monster Manual and it's a bad caricature of feminism. But, yeah, we've got all this free speech in the past that we don't have now.
Good grief. People talked about the progressive TV shows of the 80's? You mean things like Dif'rent Strokes? Yup, we got Fresh Prince, but, imagine trying, even today, to make a show where two white orphans are adopted by a single black parent. Good luck with that.
I'm sorry, but on what planet did we have more free speech during the 80's and 90's than we do now?
