Countering Anti-Migrant Talking Points

Over at Open Left, Kyle De Baussette schools the Netroots on how to deal with enforcement-based frames  on immigration:

"I am in favor of legal immigration."
"I am not anti-immigrant.  I am anti-illegal immigrant."
"I am for enforcing the law."

Every
migrant advocate has heard these phrases or phrases like these.
They're usually used to justify the atrocities that migrants suffer in
the U.S..  People also use these statements with a smug tone, as if
migrant advocates haven't heard them before.  It's not worth my time to
keep on addressing unimaginative talking points straight from the
mouths of pundits and politicians.  So I'll address them once and for
all here.  Following is a discussion of immigration law and it's
history.
