About the only way we're going to actually have a democracy is if they consistently lose elections. That's going to mean volunteering, donating, and actually turning out to vote
He’s not being sarcastic. He’s artificially injecting sarcasm into his voice so he can say what he really believes.
Say what? Did you watch your own video? Because I followed your link, watched it for ~3min, and he is clearly 100% being sarcastic. Not just in tone of voice, it's clear from the content. No doubt about it. When laying out his "plan to destroy democracy" it's a laundry list of points from the stop-the-steal bullshit. Among that:
Ban paper ballots
Replace with mail-in voting and dropboxes
Remove election day
No voter-ID requirements
Arrest opposition leader 4 times (this is a Trump reference)
Imprison protesters who don't like democracy being abolished (January 6th reference)
Flood the nation with millions of "invaders" to vote in their favour
All things the Republicans accused the Democrats of doing during the 2020 election. Then he ends with saying:
This is their "democracy" [doing air-quotes]. This is the regime we will overturn. They say democracy but they mean authoritarianism, and we know it.
I mean the guy went off the deep end and is obviously insane, but there is simply no doubt that he was being sarcastic here and that the measures he cites are not his actual plan. A Republican letting millions of people into the country voluntarily should have given it away to even the densest of viewers.
