All of this is from @Positron - I just can't quote him because KF spazzed out. I quoted the last image because Positron said something relevant after it.

Your "3 year old nephew" is not going to die of the kung flu because the only children it kills are some combination of asthmatic, overweight and immunocompromised. I can understand why he might be overweight, but I'm not sure he's any of the others.

"The survivors of [my] generation" will take power, as every other generation has beforehand. While I'm not sure we're going to start massacring our olders, we might make an exception for Moviebob.

David Hogg is incredibly naive if he thinks the party he's spent the last two years yoking himself to will do anything about taxing billionaires.
Moviebob fails to realise that if "populism" is the same as fascism, AOC is therefore a fascist. On the other hand, he probably
wants that to be the case so she can serve as the Empress of Bobtopia once the mayo ghouls have been exterminated, so I wouldn't tell him that.

This is less that and more "give them an inch, and they take a mile".
Fifty years ago, these groups "just wanted to decriminalise gay sex". Forty years ago, they "just wanted to stop AIDS". Thirty years ago, they "just wanted to promote supporting LGBT in schools". Twenty years ago, they "just wanted civil unions". Ten years ago, they "just wanted to marry". If you can't see that the slippery slope is real, or that its conclusion is "we just want to have sex with kids", then you're pretty darn blind.

Do I even need to play the "replace 'Trump supporters' with 'Jews' game here"?

Let's pretend that every member of the (at that time relatively insignificant) NSDAP and that every member of the Thule Society (which was basically a bunch of students and noblemen larping as Vikings, but whatever) all fall down a cliff while practicing goose-stepping or whatever.
None of this stops Mussolini from taking over in Italy. Mussolini would be far more likely to back a German fascist movement that was led by people who were less... well, "Nazi-y" - he didn't have any special use for Jews or Slavs, but he also didn't hate them and Mussolini only persecuted Italian Jews when the Nazis put pressure on him. If German fascism looks more like the Fatherland Front in Austria and less like the Nazis, then Mussolini would have supported it far more, and a fascist state would have come about quicker in Germany. Congratulations, Moviebob, you helped fascism win!

Do people actually use "You goddam Malthus!" as an insult?
No. What happens is that people compare Bob's insistence that
wir mussen die Mayo-Ghoulen ausrotten with Malthusianism, and Bob gets mad when that happens.
