"You're perfect, the world is perfect as it is, and be proud of who you are!"

No, no and no.

"You're perfect"

No, you're not perfect. Neither are you imperfect. There just is no standard of perfection for a human being.

You might have a crooked nose. That's not perfect. Is the classic "greek nose" perfect? No. Just as your crooked nose, it simply is the way it is, that's all. If you want, you can tell yourself that it's ugly, or that it's beautiful. That won't change a thing about the nose itself (though it will drastically change the way you relate to it). It is what it is.

"The world is perfect"

There are numerous wars going on right now. We're almost done destroying our own habitat. Almost all of the universe is uninhabitable, and if there are intelligent alien beings out there, they're so far away that we'll probably never meet.

Again, who sets the standard of perfection for the universe? Do you think you know how a universe is supposed to be? How many universes have you seen, so you can compare them to each other?

The world is the way it is. You can take yourself out of the equation, strive to lose ego, and I very much recommend that path, but that doesn't mean that the world is perfect or imperfect, it just means that you stop judging it.

"Be proud of who you are"

I'm not proud of being heterosexual. I'm not proud that my girlfriend is bi. I'm not proud of my country, my ancestry, my race. Should the 19th century British Earl of Hamletshire on the Brook be proud of his wealth and "nobility"? He didn't do a bloody lot to get it.

I know where the LGBTQAs are going with their pride movement, and I support their cause on a political level, but if you take it at face value, "pride" of being homosexual makes no sense.

Be proud of the good job you do, the good service you provide. Be proud of fighting for more equality. Be proud of the love you give to your partner (and the loving, for sure!), regardless of homo/hetero/nonbinary. Be proud of your actions, not of the way you were born.
