Critical thinking exercise. I know this is kind of not the intended audience, but the dems ideology on the wall is silly really. What I want to know is this... If you own a house, there is a parcel of land and the house sits on this parcel.  USUALLY this parcel is more than just what the house sits on.  Now, you paid for this parcel of land and pay taxes on this land.  It is YOUR land, you own it.   If a homeless person or persons comes and sets up shop on some portion of your land, what would you do?  Shoo them away, correct?  Well what if another person comes and sets up shop?  You shoo them away again.  Well what would you do if this keeps happening?  Just keep shoo'ing them away, and dealing with that hassle?   You would have the hassle of cleaning up after the last person, redoing your yard/grass, whatever affects these people made.  So after you shoo one away you spend time and money fixing what they did.  Would you keep in this endless cycle?  Would you employ technology?  Build a fence?  Just let them be?  Invite them onto your property, feed them, let them live with you?   I just don't get why they would not see the wall as a positive.  Oh well.
