Because I believe in the rule of law, and this effort is simply a way to help liberals feel good about themselves.  This idea that Trump is going to take away our civil rights is pure fear mongering.  I also think encouraging illegal immigration leads to thousands of deaths and systematic rapes of women trying to reach one of these sanctuary cities run by people who don't care to understand the unintended consequences of their actions.  It also ignores how these people are expected to provide for themselves and their families since they can't legally work either.  Do you have a plan for that too?
