I found a way to quickly find out if someone is a psychopathic liberal with TDS. Just bring up the the Trump has covod news and see what they say.
If they start wishing death on Trump and his family, then you've found a psychopath. You should probably do everything you can to remove this person from your life.
It's seriously creepy just how happy I've seen some people get over this news. Ironically the people who get happy over this news tend to be miserable most of the time.
Easier one, casually mention the millions of babies murdered and then parted out to various companies.
If they are indifferent or attempt to downplay it, then they are not humans worthy of your time. You don't want that kind of evil in your life.
