You're assuming that the thing they're "serious" about is ending illegal immigration.

The bosses are serious about making the US an authoritarian ethno state.

A MAGA state first and foremost. The hierarchy is "white MAGA > non-white MAGA > white silent > non-white silent > white anti-MAGA > non-white anti-MAGA". Will they eventually come for everyone but the first group? Very likely, but there's always a priority ordering. I'll leave it to the proper historians to decide how similar this is to the state they're using as their main inspiration.

The thing they are series about is racism, and having power to terrorize anyone they deem “undesirable”, a group which may one day include you

"truly solve the problem" ???

I believe Stephen Miller want a final solution to the immigration problem.

Oh yes and he's not acting alone. The merry band of misanthropes have all but written out their intentions explicitly. And it doesn't appear just to be immigrants they wish this stuff on.

People have been worrying about "ecofascism" well then why aren't you concerned about an administration whose policy is measles outbreaks for the misinformed of their constituency? Whose health minister is a rich environmental lawyer who just so happens to be a huge fan of letting disease rip?

I should have said "truly solved their stated problem", or "truly achieve the results they claim they want".
