Immigrants who mostly came for the same idea/culture, to work hard for ones own self and freedom, letting drug lord's and Jihad's is not even the same. 50% of the muslims in the US believe a radical overthrow of the government to put in sharia law is ok. and the US muslim population is considered to be the *most moderate*, and that mark is also the *lowest belief is overthrow of government* it only gets worse in in europe and the closer you get to the middleeast.
hell i meet a bernie sanders supporter back in 2016 on my campus who was muslim and believed in trumps ban on countries with lots of terrorist *so called muslim ban* and is very basic, he even said he father fleed before the radicals took over the government and he does not want to bring the same kind of people that his father fleed for his life from and want to implement sharia law because they do not WANT TO COME HERE FOR A BETTER LIFE. they want to destroy life as we live it, which is freedom.
People also forget THE USA had it borders closed for over 60 years with no immigration before trump even *thought of doing it*
overall, immigration should be merit based and BECAUSE YOU want to assimilate to our culture and ideals, not change them into yours. a country with no borders is no country.
