It is an unreasonable protest. It is a protest saying "we don't care what the rules are, or whether easy immigration is good for the country in general, we just want things our way, and we will harass you until we get it." Kinda like the kids in the back seat begging for a Coke until Mom stops and buys them one to shut them up.

*SOME* of the immigrants' issues are reasonable and need to be addressed...others are just "I want it my way".
