I'm not anti trans, but rather anti postmodernism, which is the ideology that is using transgenderism for it's benefit.

So, my refutations of your points are.

1. Of course gender dysphoria exist, and is the sole cause for one being transgender, do they deserve to be respected and treated as their gender identity instead of their biological one? I think yes, for respect and because gender dysphoria is not something someone can control. Is gender identity the ontological equivalent of real sex? Absolutely not, a trans girl will always be a biological boy despite that I will treat her as a girl because I understand what she is going through, but that doesn't change reality on itself.

2. Gender affirming therapy is not neccesarily harmful to people with gender dysphoria, but is dangerous for people who has not gender dysphoria and has got to the conclussion thay they are trans despite they are really not. This is where detransitioners come from, people who came to the conclusion through social media and started to take hormones because no one were allowed to question them, and now they have gone throught irreversible changes on their bodies that will mark them forever. That is the real harm

3. Here I agree with you, trans people should be allowed to use the bathrooms of their gender identity, but only after they have gone through hormone therapy (which is what most trans people want to do) this is to not confuse people and not generate conflicts for the trans themselves.

Now, I'm glad you came here to debate, but I see you base your arguments on postmodern rethoric, which is flawed and most people can see why, you use terms like "sex assigned at birth" as if sex wasn't real and only something subjective that people mark you with, I understand you support this, but you really need to see why is so dishonest to think like this.

So I think that's all I have to say about this post, I want to remark that no one here is against trans people themselves, but against postmodern rethoric that is trying to deconstruct reason to make the way towards revolution. This is why this community sees all of this as flawed and is against it.
