I wouldn't say it bothers me because what people decide to do with themselves in their own time is none of my concern as long as it doesn't affect me directly.
But, rampant stupidity
Eg. anti-vaxxers, religious fanaticism, non-binary/gender fluid people attempting to enforce their view of the world on others, male feminists.
All this during a time when we have people collecting data from smashing particles into each other at the Large Hadron Collider, stem cell treatments showing increasingly positive results in treating various injuries, and Elon Musk being on the verge of comercialising trips to the moon.
It's a stark contrast.
