But there's also a risk of people too quickly pouring cement on their identity. I'm confused about how something as trivial as selecting an option from a drop down could possibly be interpreted as cementing one's identity. If anything, the problem is the opposite one. Social media promotes a vision of personal identity where nothing is cemented, no substantial commitments need ever made, they can all be quickly undone with the click of a mouse, which means all choices of identity are shallow, superficial and ultimately meaningless.
