Is it normal if dumb people make me happy?

You know how ignorance is a bliss? Well its true and behaviors are sure contagious. So when I happen to ease drop on a dumb conversation or I'm in one with someone not so bright, I kind of get this relief like life is just what you make of it and these people are just living it. When I say dumb, I don't mean close minded people, now they piss me off. They don't have good hearts. I just mean like kind of clue -less, airheads, slow, etc. Normally, despite their lack of knowledge, they have good hearts. Especially when they know this flaw of theirs and make fun of it, just makes me feel at ease and happy. I think its cause they don't take life so seriously and just live and laugh. For me, as long as your kind and a good person with good intentions, you're on my good side and make me happy.
