When FReepers refer to events involving illegal aliens by saying things such as "Just doing the drunk driving that Americans refuse to do", they're mocking the illegal immigration cheerleaders' use of the mantra "Just doing the jobs that Americans refuse to do" in trying to substantiate why Americans should condone illegal immigration.
For a FReeper who's been a member of this forum for as long as you have, it's difficult to believe your apparent claim of ignorance as to what FReepers mean when they make these type of comments in referring to events involving illegal aliens.
Trust me, I've got it. The fact remains, the reply is imbecilic.
