The other states have no right to say anything about Arizona’s law. I know some states like in the deep South and some Western states are very resentful when someone from the outside try and interfere with their internal matters.
This is equivalent to going to a neighbor’s house and start telling them how to do things. If I had a neigbor come over and start nit picking things I did inside my house or yard, a couple phrases would be “p*** off” or “f*** off” or MYOB.
There’s a lot of Californians cheering Arizona SB1070.
Don’t pay too much attention to what our politicians say. They are part of the Treason Lobby, and that goes for the latino suck-ups in the GOP as well as the Democrats here.
