It’s not just about reputation, the forum is a public place, and everyone is allowed to express their opinion. If you see a post and you notice that there is something wrong with it, then you should correct the person. Regardless of the rank, you can’t see something wrong, and you will keep on overlooking it because you don’t want to argue about it. If you know what you are arguing about is right, then you should stand by your words. If everyone is keeping quiet even after seeing a mistake in a post, then some people will be wrong, and they won’t know that they are wrong because nobody corrected them after they made a post.
 
You arguing doesn’t give any kind of reputation on the forum here, if you are arguing and you are wrong, you are going to be corrected, and the forum was created so that we all can accumulate more knowledge about bitcoin and cryptocurrency generally, so it’s normal for people to argue.
