I still think that if a kid accepts the surname of a man who commited genocide as a first name and doesn’t change it when he has the opportunity, it’s a de facto endorsement. A lot of people go by different names than their parents called them growing up - in fact, that’s the norm in a lot of cultures. So someone will have to get used to having a different name on forms and things - lots of people do it for much less reason.
I don’t know enough about the Dominican Republic to know if there’s some cultural difference that I’m missing, though. Personally, if I met someone with the first name Hitler, I doubt I’d bother getting to know them well enough to find out what the deal with it was. As far as I’m concerned, the choice to keep a name and not fix it, which incidentally is quite easy in the U.S. - or at very least use a different name in unofficial circumstances - indicates endorsement.
This is why I’ve never bothered giving a listen to the seminal indie band Gang of Four. I’m sure they’re great - they have a good reputation, anyway - but they’re named after the friggin’ Gang of Four.
Incidentally, I’m curious about the name “Adolph”. I have to say that I would be quite surprised to meet an Adolph in the United States - it seems that even the first name has been contaminated by the association. But I’ve known a Spanish guy named Adolfo; am I right in assuming that it’s still a reasonably common name in many places?
