A direct approach used carelessly can cause the other side to feel a lack of psychological safety, which is an important characteristic to effective teams. For example, in your comment, you effectively invalidated the previous commenter's feelings and implied they were crazy for feeling that way. If your goal was to create an environment for collaboration and a meaningful dialogue, you probably failed to do so, since you come across as someone who won't bother empathizing. Were you in the same team as this individual, they would also likely be hesitant to collaborate with you, which ultimately impacts your and your team's ability to achieve desired outcomes and goals.

So, theoretically, you read that previous paragraph and didn't feel anything negative (annoyance, anger, or whatever). And if you're able to do that, I commend you-- but you need to realize that not everyone can do that. Feelings exist in other people, regardless whether you think they're valid. And if you're truly interested in solving problems effectively with other people, then you're going to have an easier time adjusting your communication style rather than telling someone to feel emotions in a way they may have no control over.
