I am afraid that if you start a political thread, you will get many comments about how "Cthulhu always swims left"

Just out of curiosity, I looked at the latest politics thread in Vaniver's list. Despite being explicitly about NRx, in contains only two references to "Cthulhu", both by people arguing against NRx.

and anyone who reacts negatively will be accused of being a "progressive" (which in their language means: not a neoreactionary).

Rather anyone who isn't sufficiently progressive gets called a neoreactionary.
