>>19199717they do have principles, but their principles aren't the same as ours. ours are fundamentally built on essentialism, the idea that there are inherent properties to all things, which naturally leads to traditionalism, that there is wisdom and virtue being taught to us by the past that we must uphold and never forget and that civilization is an organic development of these traditions based on our inherent properties. gender roles are a good example of this, being social norms that are rooted in biological differences.
leftists are constructivists. they do not believe in any inherent truth because they are subjectivists (whereas essentialists are of course objectivists). this leads to the idea that if we simply construct society the proper way, we can have a utopia (communism). and that utopia is an infinite good. and anything that opposes the utopia ("fascism") is therefore an infinite evil. this naturally leads to consequentialism, where the desired or expected outcome of the action justifies the action, which is their moral principle. if you help to achieve the utopia, anything can be excused. if you oppose the utopia, they can do anything to you. even if you mean well, but ultimately harm the cause, either through incompetence of misguidance, you must be eliminated. it is a very "top-down" view of morality, where everything is reasoned backwards. opposite of that is deontological moralism, the view that the motivation and intent behind an action justifies the action, which is the moral view of the essentialist and a more "bottom-up" moral ideology
