I'm gonna guess you read one of John Norman's Gor books, probably the first in the series, Tarnsman of Gor. I only read a little of it, years ago, and don't remember any details. But "kidnapped from Earth to less advanced world", "bladed combat", "slavery", "giant birds", "misogynistic point of view" all sound like Gor to me.
OK, here is a review. Yep, I think that's your book.
