First and foremost, the people you see calling themselves transgender advocates on the social networks are just random individuals unqualified to speak for anybody but themselves with absolutely no stature within established advocacy organizations. You should be able to see pretty clearly from the tenor of my own writings on these topics and the opinions of the authors i share , that they are light years from those exceptional drama queens. the screed says demanding equal protection under the law is everybody's obligation as a citizen, but demanding special treatment is just being an asshole. For me, pragmatism always takes precedence over partisanship and principles always precede party.
I hope you realize the exact same type of argument - i.e., most people you see on social media do not represent the average person, can be applied to people that reject many things on the transgender agenda. It's a logical fallacy to bring up arguments such as this.
In simplest terms, the medical consensus is that sex is determined by what sort of gamete your gonads produce , gender identity is determined (as best they can tell) by a mosaic of brain structures and some people are simply mismatched between their sex and gender. Gender Identity is just as biological as your sex, but gender expression is a cultural construct and conditioning begins immediately. This is where the behavioral health issues start for transgender people; being bullied by their own parents and siblings into being something that they don't feel themselves to be. My brother and his friends lined up to give me my daily punches to make a man out of me.
I could pull a woke posture, ask you for sources on these definitions and then deem the sources as unreliable and provide you with my own sources and definitions, but for the sake of trying to actually try to debate I won't do that.
Everything can be seen as social construct. Let that sink for a moment. Laws, rules, or even something such as time (or the way we measure it) itself, are social constructs. Social constructs work because they provide individuals withing a society with guidance on how that society is supposed to work and what that society expects from them as members. And society expects you to act like the sex you were born with, because that's how nature works on Humans, as simple as that. Just read Schopenhauer's "The world as will and representation" and you might understand it - truth is what you believe (it applies to you the exact same way it applies to people that disagree with you.
With that being said, throughout history, every society had people who's gender didn't match the sex they were born with. And this was never a problem - until now. Why? Because, whether you like it or not, social constructs are based on the their underlying acceptance from the majority of the population and, while the majority of the population in the Western world probably doesn't care much about a guy that feels like a woman, they react against these concepts being pushed as indoctrination and as the "new normal", specially to their kids. I know I do.
Now, I can sense (and understand, up to a point) the incoming argument that trans people have to deal with bullying and lack acceptance by society. I get it, it's fucked up, but you need to look at the other letters on the LGBT alphabet for guidance. Gays and lesbians have always felt the same issues as Trans people, but they have somehow overcome them. If you look at television, social media, etc, it's filled with gays and lesbians, and most people don't care and just carry on with their lives. They had a long struggle for acceptance, but they were able to work their way through society norms, mostly due to the fact they don't reject who they are and they can still be functional members of society, even exhibiting "weird" traits. Most trans people can't do that.
The human society is based on hetero sexuality, because that's where its own existence as species and society relies. Anyone unable to understand this is rejecting what Humanity is all about. Can we evolve? Sure we can, and we should, but we should not compromise what makes us Humans.
Marxists argue that
the nuclear family performs ideological functions for Capitalism – the family acts as a unit of consumption and teaches passive acceptance of hierarchy. It is also the institution through which the wealthy pass down their private property to their children, thus reproducing class inequality. Their take from this??? Family should be abolished. And what better way to abolish family than normalizing something other than hetero sexuality?
I don't have a problem with gays, lesbians, bisexuals, or whatever. But I do have a problem when the powers that be trying to impose a new social normative (construct) because they know that an individual without a family (or strong personal bonds) is easily manipulated.
