My first impression of "The Right to Your Opinion"

 My first impression is that I agree with what the article is saying so far which is that your are entitled to your opinion but you can't use that as a way to settle argument or prove that your are right. For example, two people are having an argument on whether the Earth is flat or round. Person 1 says that the Earth is round, while Person 2 thinks its flat. Person 1 has credible evidence to back their opinion, but Person 2 doesn't so they say, "I have a right to my opinion". This proves nothing or serves as any evidence for the argument. Anyways, that's my impression so far.
