If you are incapable of identifying some of the insane positions that clearly lost them the 2024 election, I'm afraid you may be in a bubble and no amount of someone explaining it is going to help.
There are positions which I think are dumb, or potentially harmful, or counter to what I believe, etc. But there's rarely been a position I consider "insane" (from all parties!).
If you're immediately jumping to calling every position you disagree with "insane", you're just being hyperbolic.
