They don't hate Talos, it's more a matter of their ego.

Remember the elves' claim to fame is that they believe they are direct decedents of the Aedra. The Aedra allowing a human to join the gods means that they are on equal standing, or at least close. The Thalmor just decided it didn't ever happen to preserve their world view of being the master race and crap.
