It's wrong no matter who does it.

Just would like to see people be honest and admit that it was not only Trump that "put kids in cages" and there's entirely legitimate reasons to put kids in temporary holding while sorting out their immigration situation.

Why does it matter what people were doing before?

they don't have any power, only the current president. Claiming Obama did it, and Obama was Jesus, so it must have been good, sounds really strange coming from the group who claim Obama is the antichrist
