It's because everyone is entitled to their opinion and they haven't necessarily done the work necessary to come to a nuanced understanding of the world. Take a random visitor to HN and ask him or her what they think of the changes in Golang's garbage collector.

What you think about the person in the Oval Office isn't something that you need academic or professional rigor to have a viewpoint on. It's part celebrity and mixed up with political ideology so people aren't usually shown that they don't actually understand what is going on. Plus, HN is popular in USA, Russia, Israel, Germany, Canada, Japan - each with their own viewpoints and lack of shared cultural understanding.
