Say something like this to them: "Yes, we live in dangerous times. I believe he was signaling to Nazi terror cells all across America that now is the time to begin the purges. What are you doing to keep yourself safe? I'm here if you need advice on what kinds of guns to buy."
I have done this. Do you know libtards respond? They get mad. You know why they get mad? Because anger is the brain's response to cognitive dissonance. One part of their brain "believes" Elon was giving a Nazi signal to millions of fascists that the Reich begins NOW. But that's the social part of their brain that seeks affirmations from other libtards that they are good people. But the rational part of their brain, the part that determines how they manage their own resources and plans for the future is saying, "Nah bro, this is all some gay bullshit, even if it's fun to pretend that Republicans are Nazis."
Same deal with trying to teach them any degree of online independence or opsec when they insist that they're simultaneously both not afraid of the evil online trolls and doxxers but also shaking in their boots and afeared for their lives over it depending on who they're trying to convince that day, and they are completely deaf to suggestions.
Such as
"Hey you know how to really screw over megacorps and starve them out? Not using their shit and using alternatives that don't give them a dime or a drop of your advertising metrics and blocking ads." and they're too lazy even on a slacktivist scale to even go that far.
"I hate the big corporation! But not enough to do anything about it!"
They're also inside out retarded on their perceptions of public VS private spaces. And they are anti-government in lip service only, even when the government changes hands to someone they don't trust or like they still trust everything that is basically pipeline straight to the government.
My phone is spying on me? Well I don't have anything to hide/that sounds crazy fr fr.
My TV is recording my conversations?
And out of their mouth just like their boomer parents
"Well I wanna watch muh shows." because anything else is simply too much work.
Your own privacy away from the prying eyes of the eternal reich apparently is just oooone little bridge too far.
I only bring this up because turbolibs insist that kristalnacht for anyone left of reagan is right around the corner and that black mirror is literally coming true and despite this, keep filling their houses with bezos brand backdoors while saying he's a evil genius lex luthor nazi slaver that you can't trust. And attaching their real names and faces to anything and everything as they onedrive pictures of their spread ass and post fedposts on facebook.
And reminder, these are the exact same flavor of people who still shit their pants when their publicly posted social media posts and comments and profiles boomerang back and bite them in the ass and scream about you epicly e-stalking them for linking them to something they posted on the world's largest frontpages yesterday which shows them being a retard or malicious.
Again, deeply unserious motherfuckers.
and Maribel Vance (3?). Less of an age difference than the one between Donald and Melania, way less. And when Maribel's 18, Barron will be around 33, and just about ready to gear up to run for President.
