People who treat Markiplier as a clone of PewDiePie when, aside from the fact that the two play trendy/modern cult classic games and are friends with each other.
PDP is Swedish, makes offensive jokes, and is loud.
Markiplier is American, makes immature jokes, and makes funny noises.
Not to mention, different personalities and all that.
Then again, there's just people out there who are like "EVERYTHING THAT IS POPULAR IS TERRIBLE AND YOU ARE TERRIBLE FOR LIKING THINGS THAT I DON'T LIKE" and they're funny because they're narcissists.
I have a new favorite word, by the way. Narcissist. Describes my father well.
