Yes, that's correct. Why is that an interesting conclusion? Trump is a neo-nationalist (with or without the appended socialist, take your pick), not a conservative. It's notable that the only remaining resistance against Trump in the Republican Party (represented by, e.g. Nikki Haley) are a coalition of conservatives.
Depends on what your "real' conservatives are keen on preserving. Taking the torch to things one professes to love - things like liberty, human decency and the core tenets of Christianity, that is the opposite of conserving these things.
People can delude themselves that defending their own narrow interpretation of what these concepts are supposed to mean is the noble end that justifies a lot. But in the end, it's very simple: what we are and what we bring into the world, is a result of what we do, and not of what we intend. Sowing hate and chaos is just that, and which radical end of the spectrum your justification comes from just does not matter very much.
