I think that was the point of his gesture. For too long, people have been worried about anything remotely associated with Nazis and Hitler, including salutes, symbols, names and even nationalities. The amount of racism German people still endure today because of that short period in history is tragic. Hitler's short regime ended well over 80 years ago, and the crimes of the Nazis have long been paid for. We have today worse criminals than those Nazis, who are still walking about free, inciting even worse genocide and obtaining pardons and protections from prosecution from sitting presidents (and often claiming everyone else to be Nazis!) This is what we should be watching out for and aware of - those who would unjustly harm other human beings for illicit gain or political reasons, not some harmless gestures or benign symbols.
