EDIT: From what I can see, your post history suggests otherwise. Still, though, I'm growing rather tired of the misappropriation of the Gadsden flag -- it is not a conservative symbol.
The joke is improperly founded, imo. The post's title "Kinkservative" more or less proves that the joke is founded on the presumption that the Gadsden flag is some auth-right symbol, which it is quite far from being. All this post does is push a narrative that the Gadsden flag is something that it is not. I don't want to see it be twisted into something opposite of what it fundamentally represents.
The Gadsden flag is fundamentally not a conservative symbol, so I don't know why it's being used, and treated as such. This post, and meme is presuming that the Gadsden flag is fundamentally represents those in the alt-right, auth-right, conservative, etc. circles. I have no idea why it's popped up in groups like the "proud boys"; they're idiots if they think it aligns with them in any shape or form.
The only way to prevent that from happening is for people to stand up for their true meaning, and to consistently, and publically denounce their misuse. The best way to cure bad speech is to use better speech.
