@JoErNanO, you are not precluded from participating on your winter holidays; why should others be precluded from participating on theirs?

I think your analogy is wrong. It's more like having a documented evidence of the cop seeing many people speed (say in a small town), yet only stopping out-of-towners to give them the tickets. Such discriminating practise would likely be illegal at least in California, and likely in other states, too.

I've added the background you've requested. (I still don't particularly see how such background is specifically relevant, though, especially considering the other question mentioned.)
