The culture that the left created of painting the right as morally evil / repugnant / deplorable has truly backfired. Political Correctness not only created a Streisand effect, but it also created a martyr mentality for right wing ideas.
The sad thing is that the left learned absolutely nothing from 2016 strategy-wise. I remember explaining to my leftist friends at length why people would vote for Trump. They finally understood, I thought. Then 2020 rolls around and it's like they forgot everything we discussed. Back to the deplorable playbook.
