So much for the "we're not prejudiced against Mexicans, we just want the laws enforced" crowd.
The Irish also don't use the ERs as their primary care physician, insist on government services in Gaelic, mooch off the taxpayer, harbor reconquistadora intentions or demand affirmative action hiring preferences. If the number of illegal Mexicans were somewhat comparable to the number of illegal Irish, the whole thing would be a non-issue.
Thems the facts, jack, not racism.
