I used to be like these types, and then I realized a lot of leftists, or more specifically Marxists base their entire political ideology off of theory that’s like 200 years old. Marx was writing at the peak of the Industrial Revolution probably when capitalism was in its most grotesque form (child labour, no regulations etc.) there’s no way in hell Marx could have ever imagined the complex world we live in today.
And also evolution is false because On the Origin of Species was written 200 years ago and there's no way Darwin could've accounted for all the complexities the molecular biology revolution revealed in trait heritability.
