Slavery was legal too.
++++++++++++
Exactly. Just because our overlords have decreed that this group of "illegal immigrants" are now "legal" does not make it right for the people of Springfield nor the citizenry of the USA.
The things that these government career criminals are now making legal is precisely the matter at hand.
Prosecuting Trump is legal
Opening the border is legal
Stealing <$1000 from a business is legal
Migrants house squatting and claiming ownership is legal
ETC. ETC. ETC.
When illegal activity becomes legal then societal breakdown will soon follow as police are no longer needed (obeyed).
