This repeated pattern of referring to any mention of bad consequences caused by immigrants as scapegoating, is an ad hominem tactic, which fails to rise to the plane of rational dispute. To set up the entire class of immigrants as magically incapable of any blameworthy acts, as if 9-11 were not carried out by immigrants, is grossly irrational. It is a confession that there aren't any attractive arguments for mass immigration into a welfare polity. The reason that immigration restrictionists single out the immigrant for special censure when he eats up net public subsidy like a hardened predator, is because it is easier to get the public to accept state action against him, than the comparable classes of citizens. It is also natural to militate against the increase of evil. Everybody does it, why can't we, is not a moral argument, and does not provide any excuse for the immigrant who wants to increase the evils perpetrated against the net taxpayer by the tax swilling foreigners here.
