I lean libertarian, but sometimes realty breaks that. True libertarianism dictates that I can ban whomever I want from my shop. But in reality most of the bans were of the 'No Negroes' variety. I would love to think that the free market would take care of discriminatory businesses, but history shows it will not. I agree that the true issue is ultimately monopoly: if a town has 10 newspapers and one goes democrat-leaning, no one would really care. But it's different if there is only 1 newspaper. I worry that there can only ever be a single Friendster/Google+/Myspace around, because people will always gravitate towards the most popular one.
