And you must have missed my post, then. 

I will reiterate my point that you've been a member since August 2017 and have made only 631 posts.  What are you expecting?  It isn't supposed to be easy to earn merits; that's the whole point of the merit system, to suppress shitposters and reward members who put in a decent amount of thought and effort into what they're writing.  I'd say you have a pretty good merit/post ratio.  I've certainly seen members with ones that are a lot less.
