@whatsup,
Actually no idea what's happening out there! Personally I hate to say, he is white, he is black, he is an European and he is an African or Asian! Likewise, we are all humans that's how I feel! But some people don't know it well, so terrorism and such kind of mental disorder situations could arise in any where on earth!
When national anthem plays I prefer stand up! If someone kneel I don't know what he is trying to tell by kneeling for the anthem! I prefer stand up and I think that's the best way to respect it as a nation!

Cheers~
