When two or more people want to show they're right, it's okay for them to have discussions, even if they start with disagreements. This happens a lot in a forum, which is like a place where many people with different ideas come together. It's good to see people sharing their thoughts.
But it's not a good idea if someone argues without really knowing what they're talking about. Before starting an argument, it's important to have some reasons or points to share. If someone argues without any good points, it might be embarrassing for them. So, I believe experienced members won't start arguments without having something important to say. It's like having a good reason before saying something in a discussion.
