Hyperbole is often simply sloppy use of language and depending on the topic could be dangerous as all get out.
Don't disagree with you there. I'm not a fan of hyperbolic language and it absolutely can cause problems.
However, here's the issue...
The problems posed by sloppy language is very different than the problems posed by literal language.
I.E.
I say the following about a friend of mine: "I don't want it, but he's going to **** me in the ass tonight"...
If I'm being literal with my language, the problem presented is that he's going to rape me. That's a problem and there's all sorts of manner of recourse that needs to happen there, none of which really have to do with HOW I'm talking about it.
If I'm being sloppy with my language, and in reality he's planning to take me out to the bar with the intent to get me **** faced drunk, then the problem presented by my language and the things that need to be dealt with are very different.
Trumps continual and repeated use of hyperbole and heated rhetoric is definitely a problematic thing in my mind. However, it's a VERY different problem then is presented by those who continually attempt to take him in the most literal and problematic ways possible...and it's a problem that has a very different set of solutions and consequences as well.
Pointing out that it's hyperbole isn't necessarily saying "it's okay". Rather, it's saying that the problems people are pointing to, or the supposed consequences to those problems, are incorrect because they're predicated off of bad logic (that it's literal, not hyperbolic).
So I don't disagree that sloppy use of language can be dangerous...but the fact it's dangerous doesn't justify pretending that it's literal. If anything, pretending that it's literal is actually presenting double the amount of danger, as it keeps the person from addressing the actual issues of the sloppy language while at the same time having them focused on a problem that's not even there.
