Less that God hated Esau and more that God knew he was a dumbass who couldn't be trusted with anything important. He clearly didn't approve of how Jacob took advantage of his moronic older brother either.
My current understanding is the Edomites are obviously the descendants of Esau.
God stated himself he hated esau and that his brother Jacob would rule over him. Esau rejected his birthright abd married into the Canaanites which was a no no. Abraham and Isaac both told their son's not to marry a Canaanite.
Anyway the Edomites ended up mixing with the kahzars and renaming themselves jews after they decided to adopt Judaism.
I am still tracing all this stuff but nostr:npub1j3y8d5jh5782qj9ppsse2udcukwpwrl746fa4zswj98rlkjvxhrqzwxz5r is probably more well versed and may be able to answer more thoroughly.

1. Why do you doubt God hates Esav?
2. Why do you think Jacob took advantage of him?
3. Why do you think God disapproves of this?
