Do you think people just hate the guy for fun? This isn't team sports, he's a disliked figure for many legitimate reasons, whether you agree with them or not.
I have yet to see a modern conservative position that is more backed by real world evidence than whatever more progressive position it opposes.
Climate change? Denying overwhelming scientific consensus. Gun control? "It doesn't work", even though it works in every other western country. Healthcare? "But the death panels will decide if you get to live", they don't exist, and are used as pretense to ignore all those people who die because they can't afford treatment. Car infrastructure? It's literally better for drivers if more people are using transit or cycling. Student loans? I don't even know what the argument is here except "I had to pay them so everyone else should too". The money certainly isn't going towards the teachers.
Some of these are US specific, but the sentiment is the same everywhere. The list goes on and on. If someone refuses to listen to any reason or evidence and instead bases their worldview on only their own, limited lived experience, why shouldn't they be characterized as a moron? And if they understand that their view isn't based in reality and they hold it anyways, why not call that actively malicious?
