It's not the 1/<big number> that annoys people. It's the "claim the heritage because of the results, but otherwise didn't know about it, or have any real relation (demographic, cultural, etc)" part that annoys people.
And when someone is called out for this the inevitable response is "blood quantum is deeply offensive" crap which misses the whole point. If you sever ties with a culture for many generations you cease to be that culture. Someone who's great^N granddaddy banged a slave is no more African than an Nth generation American is <insert European culture here>
