Hitler was involved in socialist politics, he just disliked jews, same with Stalin, he was quite happy to hate on jews. Most people just copy views of those around them, I've know right wingers who whinge about people claiming benefits, while happily inventing conditions to get special treatment at work, yet complain about others doing it. Left wingers are just as happy to group all immigrants as homogenous group of people as right. This whole idea that right think this, Left think that, is a stupid mentality.
