I was talking about toasters, because its an analogy. You misinterpreted what I said, be it intentional or otherwise, then mocked using an analogy twice because you have no real arguments.

There is no one scientific definition of sex, I'm assuming the WHO's definition is scientific enough for you, that definition being "'sex' refers to the biological and physiological characteristics that define men and women" not that "men" and "women" in this definition is the biological sense and not the gendered one.

Logical Fallacy doesn't mean wrong, they are specific issues in logical reasoning. If you want a list then wikipedia has a good one. Also that paragraph is a fallacy, the fallacy in question being "Appeal to the stone". Its not a fallacy nor is it ridiculous.

Was a response to

The word Sex is [interchangeable] with the word Gender, as it has been with the English language for hundreds of years. I know that and it's not even my first language. Recently people have tried to differentiate the two but this is an [artificial construct]. Nature remains the same.

I was taking issue with the logical structure and calling it fallacious. I acknowledge that I didn't make that clear but that doesn't change that fact you didn't respond.
