I think quite a bit of the concern is the lack of due process, the jailing of people for an an indefinite period in a random country, the detention of legal permanent residents and US citizens, the willful disregard of court orders, the use of immigration as a cudgel to attack universities, defining protected speech as 'illegal' and grounds for detention, deportation, or imprisonment.
these things and others make one not like the other at all
put another way, was it really worth trashing the constitution and due process to get a 29% increase in deportation rates?
Well the law to allow deportations without due process was passed by congress under Clinton as I understand it.
The main difference with Trump up to now has sensationalization of it and pushing the legal boundaries of those immigration laws.
Trump pushing the legal bounds on due process is not too different than when Obama pushed the legality of murdering of an American citizen without due process. Except Trump sensationalizes it while Obama layered it with a vaneer of intellectualism.
