I am not so sure . I swing from genetic to mental illness to explain leftists. Maybe that is a difference without a distinction.
The level of cognitive dissonance and ability to stand their ground when faced with facts is quite amazing.
The fact that some leftists produce conservative offspring, my favorite is Juan Williams, may be explained with a regressive gene possibility
Leftism is after all an easy gutless path.
Overall I fully support this new trend
There are many anecdotal tales of conservative kids going to college, then coming home on Thanksgiving with blue hair and woke values.
