The government mandating what products and services citizens should buy. In the case of the Catholic Church, it's been suggested that going forward they needn't hire employees that don't have the same values and belief system as the Church. How many law suits would that generate, denying employment based on ideology?
If a government controls healthcare, it controls every aspect of every citizen's life. Every citizen will have to obey the State to get health care. Guns are unhealthy. Ban them. Religion endangers the health of women. Suppress it. Leftists/Democrats have done very well suppressing free speech with political correctness, to the point now, if you call a black man "Juan" without the correct inflection you're a racist. Traditional press has given up it's freedom; it willing and with joy does the bidding of the State. Pretty much us in the blogosphere are what's left of the free press, and the State is doing everything it can to get control of that.
