People have opinions. Sometimes, missing the opportunity to understand the other side of the equation, they attach an oversimplified label in order to make their opinion seem obvious and correct. Usually, though, it is an honest expression of their opinion however much they are ignoring the other opinions around them. As you correctly point out, it is very common. You can choose to break the cycle, if you like. Acknowledging the other person's opinion as valid is the first step. After that, you may or may not want to encourage them to expand their view. However, if you think that the other person is unable to understand this point you may choose not to waste your time. I suspect that you could find a simplified label to describe the comment of the parent post, but perhaps it would be better to consider their opinion as valid and move on.
