This is a common trope employed by progressives. Everything they do is experimental, thanks to postmodernism. It's the kind of thing they'll ridicule others for if they "don't get it" despite the fact that there's nothing to get.
In quite a few videos, Harris presents himself in bizarre ways, little of which make sense. It's all for the sake of trying to appear like he's some kind of deep-thunk artiste. Best not to even try to think about it since that's most likely the kind of reaction he is going for--he wants to make himself this enigma you need to figure out. In some ways the presentation is also pandering to his base, people who consider themselves highly intellectual and artistic because they identify as gays, trannies or many other "anointed" persons. The weirdness is something they latch onto and eagerly pat themselves on the back, believing themselves all the more enlightened for partaking in it.
