This constant refrain that "those people are not conservatives" is getting old. If you're suggesting that only a tiny fraction of actual conservatives exist anymore, then maybe you need to take a step back and rethink your understanding of conservatism.
Conservatives have a range of beliefs, and not all are lockstep with Trump. There are traditional conservatives, fiscal conservatives, social conservatives, and yes, the MAGA crowd. Painting them all with the same broad brush only shows a lack of understanding of the nuance within the conservative movement.
And no, not everyone who identifies as a conservative supports every policy or action taken by Trump. Some are very critical and are pushing back against certain overreaches and centralizations of power.
In short, lumping all conservatives into the "Nazi" category or as some dying breed does nothing to advance any meaningful dialogue. It just deepens the divide and promotes more misunderstanding.
