OK - avowed NOT A NAZI here.
I think the cross and skull could easily be used as gang symbolism to represent the 1 and 3. It's not that far fetched.
Personally I never looked deeper than the poorly photoshopped MS13 on his hands and I thought it was ridiculous Trump would believe it. But now that I realize the MSPaint is labels for the symbols:
-M on marijuana
-S on a smile.
-1 on a cross.
-3 on a skull.
it does actually kind of make sense in the cryptic symbolism of gang tattoos. If I were LE I would 100% believe that to be a marker of MS-13. Especially since MS-13 is notorious for using publicly visible tattoos to brand their members as a way to intimidate the public and prevent members from being able to leave.
I think Trump et al are absolutely going to do horrible things. But they're starting with sympathetic causes and choosing their targets so the lines are incrementally crossed one at a time. In the case of Garcia he has two very important features, 1 - he is not an American citizen, and 2 - he (probably) is actually an MS-13 member. (And it really seems like Bukele wanted him in particular, even having reached out to Trump prior to inauguration.)
But the next step is to deport citizens as we've seen with those little girls getting deported with their mother. They use that as the excuse, but the fact is at least one of those girls had a father in the US who was a citizen and they should have had the option to stay with him by default.
What comes next? Deporting citizens who are just criminals? I bet Trump is going to find someone (brown) who is a violent convicted criminal. Then the next will be someone (brown) who is a non-violent convicted criminal. Then someone (white) who is a violent convicted criminal. Then fill in the blanks until we get to someone who was never convicted of anything except not bending the knee.
That sounds nice and all but linux still is subject to exploits and the open sourced nature of it makes it an enticing target for state actors to include extremely well made obfuscated exploits. I dont know how to win here, tbh.
