I answered that question a half-dozen times already: the difference is that this guy also opposes legal immigration.
it doesn't matter why people want it enforced.
I matters quite a bit. If the motivation is racism, then enforcing immigration law isn't the only action one will take; one will also do rotten things to american citizens in the hated group. For example, this guy states that "his" job is being taken by illegals--but how does he know they're illegal? Has he seen their green cards? Did he see them sneak across the border? Maybe some are illegal--but are they all illegal? He seems to think they are. Why? Because his real objection is to job competition, not to illegal immigrants. He is opposed to anyone who takes a job for lower wages than he would like to receive.
How do you know so much about what he's going to do? If he does other "rotten things," have him arrested. You can't have someone arrested, and you shouldn't care, if someone opposes immigration for any reason.
Because his real objection is to job competition, not to illegal immigrants. He is opposed to anyone who takes a job for lower wages than he would like to receive.
Assuming everything you said is true, so what? Part of the basis for the immigration law is to keep American wages up. You might disagree with the object, but you can't disagree with the law's enforcement as long as it's valid.
