why are there double standards?

Because of hypocrisy.

Humans lack accountability

I have no idea.

People don’t believe equal rights and equal responsibilities are the same thing. And it’s wrong.

Those who employ them are motivated by the need for trickery, dishonesty, and cheating.

Without them there would be no standards at all :)

Aren’t there (now) as many standards as pronouns? 🤔

we allow it

That is an idea proposed that allows for personal interpretation and careful thought, the word standard is the tricky one, implied absoluteness, which is not true

Sexism. Just meme away the problem and laugh like a murkan. You don't have progress, you have memes.
