> Who gives you, or anyone else, the right to "create a world" in which I am a member of and can dictate what I can and cannot say?
"Dictating"? You're not being required not to say words. People are suggesting it might be inconsiderate. Although I suppose that eventually it might become culturally unacceptable.
As for 'the right to "create a world"', nobody has a "right" to change culture, it's simply a thing which happens. Some people attempt to influence how it changes.
Though another answer might be that everyone has the right: everyone has the human right to free speech, and speech affects culture.
> I see this in our next generation and this trend is most troubling indeed
Culture shifts are nothing new. People believing they can change culture, and doing it, is nothing new.
