It might be weird or not depending on how you frame it. Asking “what do you think about the current president of the country you’re entering” might be a pretty benign question for a border officer to ask. Or it might not, depending on the exact wording and context. Hard to judge without seeing the actual thing.
The current context, in case you forgot, was that the trump admin is making direct threats against private citizens who engage in constitutionally protected activities, like speaking and like gathering in a protest. The context is that "getting detained" is half a step away from "getting disappeared".
I get that you don't think this is a problem. Just remember this when you are looking for someone that you can't find anymore.
Edit: to be clear, I think Hasan is a fool, but detaining him still smells like a political purity test
