I have always thought those that support illegal immigration ARE racist and conversations with them has not changed my mind. Supporting illegal immigration is racist and is as close as you can get to slavery conditions. Illegals are exploited, lied to, treated inhumanely, transported in downright life threatening (indeed many do die in the process) conditions and abandoned in the desert to die. Many are held against their will while families are forced to pay ransom- sometimes above the agreed upon smuggling fee. Many are forced to smuggle drugs to get here. Anyone that claims to support illegal immigration for humane reasons is clueless and comedic.
Back in the 1850s a big argument slave owners used to use was they couldn't afford to employ free blacks or whites on the plantations, because the wages would put them out of business. How many times have we heard that same argument used to justify the current broken immigration system? We had a civil war that proved how bogus that argument was.
