The phenomenon I observed in the race riots in my first two years of High School was that if black students could 'get away with' anything short of a Federal Felony because they had "equal rights", It didn't take long for white students to adopt the mentality that "Well, we have 'equal rights', too!"
Chaos ensued. State Police walking the halls of a 1200 student school with all but two entrances chained and locked shut (in violation of Fire Codes), and even that could not maintain order.
(Thanks,Mom and Dad, for getting me into a private school!)
Now, it is can used to roll back genuine infringements on the legitimate RKBA of citizens, because there is no way those here illegally should have MORE rights than those who are citizens. (and if the illegal aliens show up with full auto?)
