That has nothing to do with immigration status.. hell drive into any back woods community around the country and you'll see people whose family has been here for generations act worse than that. I know of one old lady a block a way from me in probably a 500k house that almost describes the family you had to live next to.
The point was...........legal or illegal, why do we NEED people like that to immigrate here? Do we have a shortage of offensive people? I think not. Immigration whould be based on whether or not they have something of value to add to our society imo.
