Obama as well, but this is enough to prove the point.
You said that illegal immigration is a cause celebre of the left. I asked for a demonstration that the left had spoken positively about illegal immigration. All of the links you provided were of people speaking negatively about illegal immigration.
So how can illegal immigration be both a cause celebre of the left, and something that the left condemns?
Have we misunderstood each other?
Could you please point to any of them speaking positively about illegal immigration, vs. speaking against Trump’s racism and practices such as separating young children from their parents at the border?
