I am (and I am a Trump supporter.)
Reading your post... it sounds more like you do not support deporting illegals at all... only in the case of them being criminals, which everyone can agree upon... nobody is arguing for illegals who are also criminals to stay here... those always get deported/extradited
If you support letting them stay when they have an anchor baby, or if they are benign, or if they have useful talents/skills... then you support letting them stay, not deporting them... hate to break it to ya
I've said before that I would prefer, as fellow countrymen, many of the Mexican family people I know to many of the mentally and physically damaged, spoiled, lazy, indoctrinated, low-info losers who are native born. As an example, note that Sanders acts like a magnet for such people.
Don't forget that people who accepted welfare of various types would probably not be allowed back in, or if they are, it would be at a lower priority. I had thought that it was loony right-wing hyperbole that the Left was deliberately importing people who were prone to and encouraged to be dependent on the state in order to swell the ranks of Democrat voters and achieve other objectives (esp, Cloward and Piven.) I now believe that that might be exactly what has been going on over the last 7 years. My policy would be to reverse that.
I would feel somewhat sorry for the people who are used as pawns in the game and migrated back and forth, but they got some benefit for a while complements of my tax dollars already, and Mexico is not Hell. If it is, they should go back and help make it better.
Edit: added link Note: For a period of time I disregard Cloward & Piven for the sole reason that I first heard of it from the pie-hole of Glen Beck who I did and do detest. 'Agenda 21' similar. Note to fellow 'reformed progressives' or those in the process: A powerful strategy is to encourage or demand that people intellectually box themselves in and not explore ideas presented by those outside of a defined 'safe zone.' Recognize and reject this for your own good and the good of society. I think this is also the reason behind the increasingly powerful taboo against 'talking politics.'
