Let me begin by saying I'm an old lefty. But even I get annoyed by self-righteous social justice warriors.
It's also self-defeating, as any moderate within ear-shot will think you're an ass, and vote against the left in the privacy of the voting booth.
I believe "virtue signalling" helped get Trump elected, by alienating some voters against the Democrats.
So what is "virtue signalling?"
Here's some background on the following video.
The country of "Kekistani" does not exist. There's no "Kek" flag. There's no refugees. It's simply a way of a conman making a social justice warrior look dumb.
It all takes place at a "Don't shoot" police protest, with many anti-police antifa protestors covering their faces.
A conman, who appears to be of Mexican descent, wears the fictitious "Kek" flag as a cape.
The female dupe obviously has no idea why the man is wearing an unknown flag but assumes it's bad. She's been duped into virtue signalling.
Conman: "Your people are the ones covering their faces. They can't even stand up for what they believe."
Dupe: "I'm right here ... so you can't stand for what you believe."
Conman: "What's wrong with the Kek flag? Explain it to me?"
Dupe: "You don't even stand for what you believe."
Conman: "Yeah, I can. I'm right here. What's wrong with the Kek flag?"
Dupe, obviously stumped, because doesn't know anything about the fictitious flag: "You tell me man."
Conman, saying truthfully: "There's nothing, absolutely nothing, wrong with the Kekistani flag."
Dupe: "Oh yeah. Tell the people who died under it."
Conman, keeping a straight face: "Under the Kek flag?"
Dupe, seeing cameras, enjoying the attention, and believing she caught the conman out: "Yeah, all the carnage."
Conman: "The Kekistani killed people?"
Dupe putting finger in conman's face: "You know what dude? You're a f__king moron."
Conman: "Oh, I am. OK. I think you lost the argument when you start insulting someone."
Dupe: "I think you lost your argument when you wore that flag, like a cape. You're a super Kek."
Conman: "Yeah I'm a Kekistani refugee. I love freedom."
Seeing her fellow SJW stumped, a masked dupe steps in: "hanging out with white supremists is the only way you can have your freedom?"
Conman, again truthfully: "are there any white supremists?"
Back to the original dupe, ignoring the fact the conman appears to be of Mexican descent: "you're the white supremist."
Another dupe: "you don't deserve freedom."
Masked dupe: "go give your leash back to the oppressors."
Dupe: "because you're in the flag of the oppresor. Because you don't feel oppressed enough"
