That’s fine.
Another thing society needs to curb is getting celebs to comment on everything, so attention in one area doesn’t make one into an all-knowing life coach as it seems to work for some people.
But more broadly, if you are worried that giving someone’s attention will create a large following of, for instance eugenicists, then you are actually worried about the idea already having a large support, irrespective of the person who would receive an unrelated award.
There are good arguments to be made against eugenics programs, just make them instead of trying to disappear anyone that has ever seemed to support them.
Refusing to recognise someone’s brilliance because of political ideologies is something most people understand to be wrong and in my view just as likely, if not more, to create support for that political cause than to suppress it.
