Voltaire was credited with saying something to the effect of, "I disagree with what you say, but I will fight to the death for your right to say it." George Carlin noted that there are some words you cannot say on TV. He noted that a guy in a "Western," could say, "I'm gonna kill you. And, I'm gonna kill you real slow, just like I killed your brother." But, he could not say, "I'm gonna f*ck you. And, I'm gonna f*ck you real slow, just like I f*cked your brother.
The father of a high school friend of mine was the head of Standards and Practices for CBS. He said that the rules for free speech on TV were that they were subject to "community standards. And, violating these could lead to fines and being banned from TV.
In politics "polite," language is the norm. Impolite language is common. Inappropriate language is defined by the offended party. I would rather defend a statement that exaggerates the effects of global warming than calling for the death of the Speaker for "treason." But, thanks for the cute memes. I will remember them until I log off this page.
