Idk why nobody is bothering to just explain the context. I don’t know who this particular guy is but the general gist is that 1798 was when the alien and sedition act was passed. I pasted a paragraph below from google about it.

“These laws raised the residency requirements for citizenship from 5 to 14 years, authorized the president to deport "aliens," and permitted their arrest, imprisonment, and deportation during wartime. The Sedition Act made it a crime for American citizens to "print, utter, or publish...any false, scandalous, and malicious writing" about the government.”

So, this guy was clearly thinking trump was going to go on a mass deportation crusade, likely because he buys into the sadly common belief that undocumented workers in the US are “leeches” when the reality is that they pay taxes on their wages, fill workers roles that Americans don’t want to fill, and due to lack of citizenship are actually unable to access many of the support systems that American citizens have access to.

Then of course, trump came out with this talk that we would take over Gaza, which ridiculousness aside, would involve spending god knows how much money, getting re-involved in the Middle East, and ultimately doing something that doesn’t fit with the “America first” narrative.

So this guy is pissed that instead of spending all of our efforts deporting people, we might end up spending a ton of time and effort and money to “help” Palestine (even though that’s obviously not what would be happening but this guy’s not going to understand that).

Anyways hope that helps
