The classic Republican-flavour of conservatism is dying out in the US amongst the younger generations, which means that the GOP is like a wounded, cornered animal: now is when they are the most dangerous and likely to lash out violently.

No, unfortunately conservatism is really quite seriously NOT dying off among younger people, it is rather building momentum. Fortunately progressive leftism is building momentum even faster in the minds of younger people.

What is dying off is "both sides" centrism that builds a worldview like an excel averaging algorithm over a column of cells, bereft of values, ideology, bold visions or really even anything of substance to fight for really. Can't happen fast enough if you ask me.
