Exactly --- the erase-the-borders, let anyone come here and we'll support them all if they can't manage to support themselves crowd has no clue of what they are supporting. Every open borders proponent should just move to Mexico --- maybe a city like Ciudad Juarez and take a better look at what they're proposing.
They should also take a little side trip to Tijuana. Illegal aliens bring their culture with them, recreating their home environments right in the middle of our towns. It ain't pretty. Good deal for illegal aliens, very bad deal for us, and expensive too.
