why are there double standards?

Because of hypocrisy.

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

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

I have no idea.

we allow it

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

Humans lack accountability

Without them there would be no standards at all :)

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

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