I'm genuinely trying not to be mean, but this is some of the most cartoonish "tough guy" language I've seen in a long time.
You're literally just sitting at your home 6,000 miles away anonymously goading others into amassing weapons and armor to fight one of the largest super powers in the world, talking about how you're "willing to stare down the barrel of a gun," while whining about downvotes on a website and saying that you can't participate because you might get temporarily detained at the airport.
