I'm not touching the racists part of this thread, that said;
1)"Some buisnesses close" I lived in Daytona, and witnessed how BCR(Black College Reunion) is more destructive to hotels than spring break(the next worse), Rolex race week, Daytona 500 week, Turkey rod run, Pepsi 400 race week, bike week, Biketoberfest, and a couple other special events. Its about hotels/restrauants making a profit. If the owner of a hotel wants to close it so it doesn't get damaged(as they have in the past), its his/her right! They're not closing it because of race, they're closing it because of money. If they closed it to only blacks, then they would be racist. Since they're closing it completely(to everyone), they're closing it to all. Of course there are always a few racist hotel/restraunt owners, you can't get around that(human nature).
2)"more police" If events have gotten out of hand in the past and the police do not prepare for it the next year, who do you think is going to get the blame?? If the police let people hurt themselves or others, the police department gets sued. If the police department tightens up on an event know to cause harm to people or property, then they're racists. Not really fair is it?? Of course there are always a few in the police departent that are racists, you can't get around that(human nature).
3. The press. News articles are almost always sensationalized. The press pushes the public's buttons to make money. Notice the only waitress that was quoted, had a very provactive statement that I'm POSITIVE does not reflect what other people think. I'm sure there are people who could care less about Black Bike week that live there. And granted sometimes the press reports objectively.
Just don't be so quick to assume its only racism. Sometimes there are reasonable factors. Money, liability, and the sensationalizing press all very reasonable to me.
