Colbert has no regrets: Late-night host defends controversial Trump Putin c*ck holster joke

111. I'm showing you how easy it is to be offended by nothing.

How you see those three things is exactly how others see your grievance. Cocksucker is a general insult that is often applied to gay men, but those aren't mutually exclusive. It's an insult that becomes a slur when used on a gay person, not the other way around.
It's not using sexuality as an insult. It's using putting a penis in one's mouth as an insult. You act like it's new but people have been telling each other to suck dick since Mesopotamia. I could make a laundry list of why sucking a dick is found to be degrading, but that would be a wasted effort. The real point you need to take home is that it's symbolism. Homosexuality is the last thing in anyone's mind when they hear that. It's amazing that these jokes need dissection just because people can't comprehend metaphor. Here's the joke, translated into diplomatic language: Trump loves Vladimir Putin so much, and is so grateful, and possibly being blackmailed, that Vladimir Putin can have a permanent resting place for his genitalia inside Trump's mouth. It's not sexual, Donald Trump is like a piece of underwear. And he's happy to perform this duty outside the realm of his general feelings regarding other penises, because he is unwavering in loyalty to Vladimir Putin.
But that isn't a good use of time, now is it?

Anyways your logic is backwards, understandable if someone is facing the term from the perspective of their own sexuality.

He didn't use cocksucker, and the distinction is key. Sucker is a person. Holster is an object.
