It isn't even the thinking. I've seen some questionable conservative thinking.
It is a childish response to those who disagree and/or put forth a different solution to issues and problems that exist in America.
The left has aged, but they haven't ever grown up. They meet any disagreement with their worldview with rage-filled hatred. Offer up any solution to any issue today that is not lockstep with their preferred narrative, and you will be met with all-encompassing hatred.
This has been the case now for nearly 30 years. Before, they would disagree and maybe call you a name or something.
Slowly, they have been teaching their offspring and the offspring of the world that theirs is the ONLY answer and that anyone who offers anything other solution you are met with the temper and rage you often see in 5 to 8-year-olds who have been so spoiled that they get their way simply by throwing a tantrum.
The right has had its share of hate-spewing, but most of started in response to being targeted. Now, they too are taught to hate and respond in hate.
They are openly brazen about it too. One has only to turn on the nightly news, or tune into any cable news outlet, and see it being promoted, accepted, and applauded.
