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.
Disagreeing to agree is always the best in any discussion but where this individuals deviates from discussion to reputation maintenance is what amazes me e.g Where Mr. A is saying I'm a professor so you can't correct me because I have 10 degrees and Mr. B is saying education does not matter here I have experience, I have worked for so so years so you can't correct me here. It's just so disappointing... To make matter worst it's L members that engage most this arguments.
