I just agree with his opinion
Sending merits because you agree with his opinion? I hope you're not a merit source.
You're right, I should only merit posts with incorrect information from now on.
You're supposed to merit good posts, not because you agree with user's opinion. I'm sure Quickseller will support me on that, he is against "groupthink". Also:
I encourage people to give merit to posts that are objectively high-quality, not just posts that you agree with.
