When you crush their argument, see it driven before you, and hear the lamentation of their talking points, and it still gets nothing done, you don't have much left in you to go on to the next one.
( EDIT: So, here's a recap. Identities redacted to protect the innocent and guilty alike. )
FRIEND ON THEIR WALL: "Can we X?"
ME: "Nope. Here's why. (Cut and paste from old essay written to answer this the last dozen times I've been asked.)"
RANDO FRIEND OF FRIEND: "And how often does (specific circumstances) happen? Show five examples in the past five years."
ME: "Ma'am, I don't know you and I don't work on demands. Try saying please next time. Or pound sand, I don't really care."
FRIEND: "Interesting. But Q has happened. Is that a game changer?"
RFOF: "YOU'RE EVIL!!! AND YOUR PENIS IS TINY!!! REAL EXPERTS HAVE SOURCES! YOU DEVIL WITH TWO INCHES!!"
FRIEND: "Um, peanut gallery? I actually respect Jay's work here."
RFOF #2: "Oh shit! RFOF is gonna rip your ass in half!"
FRIEND: "Jay, here's the study. (cites) If we can save one life, isn't it worth it?"
ME: "Oh, the 'if we can save just one?' argument. The one that will never need to be proven, because it's impossible to prove a negative. Here's a laundry list of all the unintended consequences, several of which have happened. Don't see the risk justifying the rewards here, mate."
RFOF #3: (Insert bullshit misleading but fits on a tshirt phrase with no citation here)
ME: "Oh, and since it took me about five seconds of googling and two minutes of compiling, here's all the examples RFOF asked for. Within two years. And I didn't even need Fox news to do it." *buffs nails*
RFOF: *incoherent screech* YOU MICROPEENED ASSHOLE! THIS WILL NOT STAND, MS. BARBARIAN!"
ME: "Bodyshamed AND misgendered by a good woke liberal? The Harem's gonna find this one hilarious. You've got some fucking salty ones in your peanut gallery here, mate."
FRIEND: "Interesting points. Got data? I'm not finding anything immediate on Google."
RFOF: "Ok, so in how many of these cases did they NEED (weapon)?"
Fuck you, Ms. (redacted), you blitheringly ignorant cumstain.
You don't get to backpedal now that I've called you out for the bodyshaming, misgendering, self-righteous lubedribble that you've behaved like thus far.
All I asked from you is manners, and all you've given me is trash.
And now that I've called you on your bullshit, you want to move the goalposts.
Sit on it and rotate."
RFOF 2: "OMFG!!!!" *faints*
ME: (Blocking RFOF as I speak) "The Bowne case is the current poster child for restrictive laws getting people needlessly killed. Everything else, I'll look in the usual suspects. But going back to 94? It's gonna be hard to find anyone that asked those questions back then, but I'll keep an eye out."
FRIEND: *surveys destruction* "That escalated quickly. Thanks for participating, folks, but I'm gonna close this thread now."
ATTACK HAREM GIRL IN ANOTHER COUNTRY: *falls over laughing*
RFOF 3-5: *Ignores Friends requests and continue blathering*
ME: *switches to DM* "Sorry about that one, mate. But I got boundaries, and, well..." *waves hand*
