Their is no objective measure of if something is a slur. Their is simply a word and some quantity of the population that find that word subjectively offensive against themselves. If enough people say that a word is a slur then it becomes a slur.

People are just insecure about gender; even though it, and all of the traits that come along with it, are entirely made up social concepts that only exist for those that acknowledge them.

Because it’s not a real actual thing, it 's entirely open to interpretation and as such some people will see the same thing as good while others see it bad. Because it’s found only with a social base—i.e. an ‘identity’ or how other people perceive you—the more aware someone is of other’s seeing them, the more likely they are to be passionate about the concept and adhere to it.

There are only two genders, no self interpretation is allowed. Far left duh.

Well, in nature there’s no genders.

We were born from buts and pieces and will go back to them, in a timespan that’s not even worth noting.

But in human society genders were created and they’re specific to the culture and society you’re in, so you don’t even get an international standard.

Take those away, though and you’re just being back to how you were born; genderless. If you were born without the rest of us, you’d.never even know what gender is. That there are specific rules, dependent on society and culture, to what you can do, wear, earn, fuck, and behave like based on other people’s interpretation of your biological make up.

You can adhere to these ideas and get upset, or not.
