If it is OK to cross the border and the US government will take you in house you and feed you, is it OK for me to:

Break into your house and wait for you to feed me?

Take your food without your permission. (It is a right.) 

If the IRS can target people they disagree with can I:

Report people I don’t like as terrorists to the FBI?

Audit Charter Cable because I think they over charge me.

If Obama can just refuse to enforce the law?

Can I refuse to have any healthcare coverage?

Can I walk into Mexico and stay as a Mexican citizen?

Can I stop paying taxes?
