Yet this is held true by the wise of Eressea, that all those of the Quendi who came into the hands of Melkor, ere Utumno was broken, were put there in prison, and by slow arts of cruelty were corrupted and enslaved; and thus did Melkor breed the hideous race of Orcs in mockery and envy of the Elves, of whom they were afterwards the bitterest foes -Of the Coming of Elves, The Silmarillion

From the fucking Silmarillion you bigoted dipshit.

That's two times from Tolkien's own writings that that orcs are bred which can only happen if there are female orcs.

Why does the existence of female orcs offend you so much? Why do you care so much that they exist? Are you that much of a sexist that you can't enjoy something knowing there's women in it of any race?

Nah, you lost the argument here, when you result to ad hominems.

You're actively denying facts from the author's own mouth. How is that not dipshit behavior?

Confirmed by books and the lore.

Prove it, actually show a passage saying that Morgoth created them out of thin air. Show me the passage where it says they don't breed. I've posted two facts from the author's own mouth and works so surely you can find something supporting your argument.

Tolkien was very specific in his language and his book are the canon

Canon is whatever an author wants it to be. Again, since he went back and retconned The Hobbit by your logic that means the LOTR trilogy isn't canon to you, or are you a hypocrite and going to conveniently deny your logic?
