People, for the most part that I can tell, are currently protesting against
- the illegal deportation of American citizens
- the questionable deportation of undocumented people
- the practice of deporting people in legal process
- and finally the practice of separating families while you do it (citizen, illegal, or undocumented)
Thus gestapo, nazi, etc
I am sure you can find someone online wanting more illegal immigration, but in my experience that isn't the case.
The Obama admin I believe still has the highest body count for deporting illegals and from what I understand did not use the above tactids. I personally liked Ws plan of documenting who is here and upping the border presence to reduce it in the future. Of course any real plan will need cooperation with other countries, synergistic strategies on drug wars, and drug use, and economic policies that reduce the imbalance.
It amazes me to this day that so many people get so emotional over illegal immigration. We have so many bigger problems in this country IMO that need attention and from what I can tell don't arouse such feelings. The perpetual victimhood angle of blaming others for our hardships is a tale as old as time.
