Yes most of the strongest have been white...but the best pressers at the moment are black...there's a west African fella called Iron Bibby who holds the log press world record at 220 ish kilo and the bench press record is held by julius maddox a black American fella..with 780 lb...
Mind I would love to see the Georgian weightlifter lasha talagadsi have a crack at the log...he can snatch 225 kilo...just shy of 500lb
