I remember ages ago when it was revealed that Nancy Reagan was consulting an astrologer and then trying to convince her husband, the president, to do or not do stuff based on the alignment of the stars, or whatever. I think that the president has the right to choose his advisers, but at the same time expect more of a president than to take the advice of an astrologer. That's pretty much how I feel with respect to Trump's handling of COVID. I ask myself why would a president consult with a radiologist about herd immunity. But of course that is his prerogative, and if I don't like it, I can vote for someone else the next time around, and while I am waiting on election day to arrive I can call him an idiot anywhere I want. Seems pretty straightforward.
About opinions, I think that everyone has a right to his opinion, but it does not follow that everyone's opinion is right. All opinions are not created equal. Sure, all opinions are equal as to your favorite color, but not as to whether the Earth is flat or not, or the moon is made of green cheese or not.
