Studies continue to show that liberalism and mental illness are strongly correlated. For example, over 50% of liberal women in the US between the ages of 20-30 report that they have been diagnosed with a mental issue. If you want to date crazy, liberal women are probably the way to go - problem is they also score low on the hotness scale.
The consensus (possibly based on data, I’m not sure) was that it’s overwhelmingly liberals who refuse to date or have contact with family and friends who overtly support conservatives candidates and causes; not so much the case with conservatives.
But, then again, conservatives aren’t known for burning down cities and vandalizing cars, either.
