Biden invited the kids to their cages. He didn't try to stop them from being in the cages. Biden is evil on this issue. Trump was trying to stop the process altogether, and so was good on this issue. But that is a difference between them. I have different views on them when they do different things; and similar views on them when they do similar things. Not so the Biden supporters. They like Biden when he is bad, and they attack Trump when he does good, because they are about partisanship not principles.
The link you gave for my post proves this.
If you think that link helps you in this discussion, then you are really trying hard to misunderstand.
