Weird in modern parlance by the laity is an expression of uncanny oddness, as per The Weird Sisters ( or Wyrd Sisters ) in the play MacBeth. It's a common reaction to esoterica which is information or knowledge that sounds odd and dangerous without understanding of context. There's intersection with secret as in secret societies like the Freemasons which are actually esoteric societies in that they dabble in esoterica (in the case of Masons, pro-tips on how to build structures so they stay up for a long while).

In context of the current election seasoin Kat Abu explains it really well ( on YouTube ), weird is not the point, and some adjectives may serve better. The point is some of the policies and statements of Trump, of Vance, of Project 2025 (and the other usual suspects, e.g. The Republican Party, The Heritage Foundation, The Federalist Society, etc.) seem odd to those of us who want to live in a functional democratic society and want a public serving government, and those policies / statements require more context than we're being given.

• Why does Trump need dictatorial powers on day one?
• Why does Trump say Christians won't have to vote again (or accuse them of not voting much when they do)?
• Why does Vance have contempt for childless women who like cats?
• Why do they (Trump / Vance / P2025) keep talking about immigration invasions and crime waves even when crime is low compared to our history, and migrant populations have significantly lower crime rates than the general population? Also it's generally a right and proper thing to provide sanctuary to refugees from abroad?
• Why do GOP officials begrudge children school lunches, or library access (even to adult matters, if they're interested)
• Why do they want to defund Social Security
• Why do they encourage police brutality on protestors?
• Why do they freak out over trans folk?

The list goes on and on, and normal Americans appear to believe it's right and proper to feed our kids, to have social safety nets, to have free and open abortion access, for education to be affordable, for workers to be able to balance work with parenting, recreation, civics and getting the laundry done. And yet, the Republican party (including Trump, Vance, etc.) seem to think the opposite is true.

In fact, a lot of them sound like an NSDAP party member trying to explain why mass executions are a pretty good idea.

So either they need to explain themselves, or we get to tag their positions as unsuitable for elected offices in the United States, especially the presidency. Weird is an easy word for it, but there are dozens of others, including just bollocks.
