Not all opinions are equally valid. Your opinions on Trump's policies are not valid because you don't know anything about his policies. There are plenty of people here whose opinions I disagree with but whose opinions are more valid than yours because they actually know what they're talking about.
I'm sorry if you were insulted when I said you didn't know shit. But since you think all opinions are equally valid, then you shouldn't be insulted when I say you don't know shit. In your worldview, your lack of knowledge doesn't effect the validity of your opinions, so you have nothing to worry about.
Some more of your "valid" opinions, I see, but just remember they are no more valid than mine! It's just that YOU don't agree with mine!
