Can you elaborate? How is critical theory affecting the policy advocated by left wing political candidates? Which left wing ideology did they promote previously which you could vote for, but are unable to now because of which specific policy? Can you give me an example of critical theory expressed by the left wing candidates in your elective district? And why these examples in particular make it so that you can’t vote for them?
