Permanently, as in, can never be used even in the far future?
All the names I'm thinking of might be possible in the far future. Hopefully by then, the associations will seem trite.
Adolf is ruined in the west because no one will ever recover from Hitler's tyranny and mass murder. I agree with a previous user that
Vladimir might become ruined, too - but only in countries that were actually concerned.
Lolita,
Gay,
Gaylord,
Jemima, and
Dick, and
Fanny might be able to resurface if people considerably "mature" along with the technology they'll be using. I'm hoping that with all of this science stuff, people will care more about the individuals with these names than the actual names.
