Well, when laws are passed to enforce one's beliefs on others that goes beyond disagreement.
Overall, I am a laissez-faire guy. I don't want government intervention on firearms, economy and yes, even in medical choices of one's own care. People have personal responsibility and have to live with the consequences of their own choices and actions.
It is funny how those on the right supposedly abhor government intervention on people's lives but be the first ones to pass laws for social engineering when it suits their own viewpoints/beliefs. The hypocrisy is amazing. BTW, it goes double for those on the left, but at least they are honest about having the government be a factor in one's life from the cradle to grave.
