They're not wanting to protect just any immigrants,  they're protecting illegal immigrants. Shameful to be protecting criminals. 

As a side note,  this is part of the anti-border Left's plan - conflate legal with illegal immigrants.  And the DP is complicit in this deception. But smart people understand there is a huge difference between the two.  Most Americans aren't anti-immigrant - you want to come here legally,  great.   But many of us are anti-illegal immigrant because they broke the law.
