The culture wars are explicitly a tool of the right to provoke fear, anger, and hate against others.
The left gets trapped in it because every single culture war issue (LGBQT+, racism, feminism, reproductive rights, freedom from religion, etc) are responses to the rights reactionary drive to claw back rights from everybody who is not a white male christian.
> The left gets trapped...
Nevermind the wedge driven when moderates who think of themselves as being on the left agree with the idea that past weak attempts to nudge things leftward "went too far", or that there actually is an issue with "government waste". Sir/Ma'am - you are complicit in moving the Overton window to the right.
