True leftism is when you reject reality, and anyone that doesn’t subscribe to your extremely niche, extremely online ideology is either a conservative or a centrist. Everyone who disagrees with you, whether on the basis of theory or history or material conditions or lived experience, is just too morally impure to achieve the same level of leftism as you, you are the One True Leftist, and you’re not going to let little things like what things exist or are possible get in the way of that.
