The dismissive rule is about dismissive posts being borderline spam. People showing up to a topic they don't care about to leave only that sentiment before absconding isn't very different from showing up, posting something completely random and irrelevant and then leaving because both are equally pointless.
But so long as it's not the topic they're dismissing, I'm pretty sure people won't get banned for dismissing someone's point. Considering you make wild claims with basically no factual basis, there's not much people can really do to you besides dismiss your craziness or humor you for whatever reason. If you wanted people to take you seriously, maybe you should put more effort into how you conduct yourself, otherwise nobody's going to hold your hand and nobody owes you their time of day here.
