Whether or not your kids are disease ridden and can cause the death of my children as a result IS MY BUSINESS.mind your own f****** bidness, you nosey, unbalanced busybody.
If you don't want to live in American, then get the F out. No one is asking you to stay.
However, if you DO stay, then you are going to play by the rules we ALL must obey and that INCLUDES helping to prevent disease from killing and crippling children.
Your ignorance of biology should not dictate the safety of others.
