In the best spirit of “it’s easier to communicate if we define our terms”, let’s discuss what it means for something to be “a social construct”.
I was a sociology grad student working towards a PhD in the field, and also a feminist theory junkie from way back when. This is my take on “social construct”, for what it’s worth:
If something is a social construct, it can still be a very imposing presence in people’s lives, something they have to deal with all the time (insofar as they have to deal with other people), so it does not mean “it’s just a bunch of easily dismissed vapor that we should all ignore”.
It does, however, mean that the way it is set up (whatever “it” may be) could be utterly different. Maybe not infinitely different — there may be some solid anchors to non-social reality that constrain the ways in which “it” can be set up. Since we’re discussing gender, there are probably some facts pertaining to sexual difference which create some constraints like that. For example, how society perceives pregnancy is something that could be set up in a variety of different ways, not just the form we’re familiar with, but it’s probably reasonable to suppose that a mirror-image world in which the males are shamed if they get pregnant outside of marriage is an unlikely one.
If someone identifies as the opposite gender, that implies that there is an opposite gender. It isn’t inevitable that we as a society would only visualize two genders, and if we visualize more than that, what the heck is an “opposite”?
If someone identifies as the opposite gender, that implies that one possible reaction to the way society thinks of gender is to identify in a fashion contrary to expectations. It may imply that identifying as the opposite gender is, itself, a social construct, an identity that is out there that people know about, that is socially available.
If someone identifies as the opposite gender, and is understood by other people to have done so, that understanding that people have is, itself, a social construct, consisting of all the expectations that beliefs and notions about exactly what it means to “identify as the opposite gender”.
We’re doing it. In here, in this thread, on this board, we are participating in the social construction. Construct is a verb, not just a noun, you know. Social constructs come from people. A social construct is a notion that is socially shared and, furthermore, is expected to be shared. If you’re in here and your individual take on what it means to identify as the opposite gender is an outlier, a perspective that is not in keeping with the one that you’re expected to have, you’ll experience social tension. People will react to you in various ways. It’s a microcosm of how people react when a person violates the expectations that people have of them based on their perceived sex, so there’s your little taste of exactly how real a social construct can be.
I’m not one of those people who go all hippy-dippy and say shit like “reality is whatever you conceive it to be”, or the social version of that “everything is a social construct, the belief systems that people have are all programmed into people who are blank slates before they’re socialized and it makes no sense to speak of ‘physical reality’, we can only perceive what we’ve been taught to perceive”, or whatever. But social reality isn’t non-real. Just remember, language is a social construct, too. You think in the terms and use the concepts embedded in that social construct. You interact with people and encounter all those expectations all the time.
