If someone were to refuse to pay taxes the Left would be livid; if someone refuses to respect the legal immigration process, the Left calls for amnesty.
My wife is a naturalized citizen from Mexico -- it's insulting when people call for amnesty for illegal immigrants while US consulates all over the world have lines around the block for people to apply for immigrant visas.
When we have military veterans that can't get decent care at the VA; I feel a huge resentment at a single dollar supporting illegal immigrants in any way.
Refugees are quite another story: refugees commonly aren't illegally entering the country, but have gone through the proper processes.
The Left supports the so-called "path to citizenship" only because the majority of illegal immigrants would vote Democrat if given the chance. Case in point: note the silence at the Obama administration changing the wet-foot-dry-foot policy for Cubans. Cubans historically vote Republican, so that policy shift illicited not a single protest from so-called "pro-immigrant" groups. A women with a felony convictions and a deportation order resulted in protesters blocking roads. Janet Reno deported Elian Gonzales back to Cuba and the Left supported that. Yet the complete opposite logic is used to support the admission of unaccompanied minors who arrive from Central American countries.
The Democrat support for illegal immigration is nothing but playing to a particular constituency that they need in order to have any hope of winning elections. Cynical? You bet. Look at Lyndon Johnson's comments about black people as an example of that disingenuous "compassion" in action.
