It's a long-tenured pseudo-con technique.
When they can't logically, persuasively refute a political position they oppose, the dismiss it with contemptuous label. For years "liberal" was such a label.
note:
"Woke" in this slang usage seems to approximate a synonym for "enlightened", aware of the pros & cons of both party's positions.
Therefore when a MAGA insults by accusing "woke", they're confessing that they are not.
Ignorance: a badge of pride for the Trump cohort.
