It’s an extremist stance. Specially considering that this is not US politics where left wing is generally just right wing and at most center. If I had to describe these parties in US political landscape it would be something like Bernie sanders left wing vs Joe Biden right wing.
Nah it’s just that the anecdote doesn’t sound like the whole truth and your reaction seems irrational and exaggerated.
If you have good character, you shouldn’t be concerned.
