People who have financial problems or religious beliefs against it are excempt. Why don't you do some research before ranting.
People who can't afford to buy the health care aren't covered by the mandatory purchase requirements, and they are able to take advantage of lower cost or free care to which they already had access prior to the new Patient Protection and Affordable Care Act.
I'm confused about why you think it's "dictatorial" to get people to simply obey the law that has been passed by a democratically-elected Congress. It is dictatorial that the government requires you to wear a seatbelt? They it requires you not to litter? That it requires you to pay into social security? These are all laws passed by the government that We the People elected. It has nothing to do with anyone being a dictator. The law was passed by both houses of Congress.
Take a stab at reading the actual law and not just the Republican talking points on it. If you haven't noticed, conservatives don't care about the poor and just use scare tactics like this to try to get votes. The Republican party only cares about the wealthiest people and corporations who pay to make sure those old white guys stay in power.
