Largely, because the Administration has taken active steps to prevent lawful asylum applications.
> and the kids will be reunited later if they are real family
Maybe, sometimes, after the recent court order requiring that; most recently prior to that the kids were being used as hostages to force parents to sign voluntary deportation agreements and give up asylum claims; during and prior to that children were deported separately from their parents and vice versa in a number of cases. And, in any cases, there was no tracking of any kind to facilitate reunification.
> not a big deal and the kids are still doing better than before
No, they often aren't; especially for the younger children, being forcibly separated from their parents is itself an enormous trauma that will damage their development (social/emotional especially for life.)
Somehow, they handled it just fine and at lower cost without family separation before. If so, why separate them except due to racism? They are now having trouble reuniting families weeks later because of improper tracking.
thinking that its racism is just you jumping to emotional conclusions
there are no problems reuniting families when they are actually families, it is when kids are alone or abused as drug mules that they have to work harder to find where to put them
they still leave horrible conditions so why arent you upset over how bad the other countries are?
Before Trump’s zero tolerance policy, when criminal charges for illegal crossing were essentially never pursued on their own and families with children targeted for deportation without criminal charges were also (since the court order limiting the use of immigration detention for children) not subjected to immigration detention specifically to avoid separation, and where active steps weren't taken to force entrants seeking asylum to enter illegally by preventing access at ports of entry, which is what actually pushed most of the families subjected to Trump's zero tolerance policy into the system in the first place.
> there are no problems reuniting families when they are actually families
Yes, in fact, there are, in the present situation.
> it is when kids are alone
Unaccompanied minors have been a particular problem at times in the past, but that's not the current issue.
> or abused as drug mules
That happens, but, again, is not the source of the current crisis.
> they still leave horrible conditions so why arent you upset over how bad the other countries are?
Most people upset about this administration’s blatant and indefensible mistreatment and hostage taking with regard to asylum seekers are, also, unhappy with the conditions in the countries that they are fleeing. Which is actually a big reason why they are upset at the Administration’s further tormenting them when they are trying to flee, and actively preventing them from lawfully seeking asylum.
it happens to families everyday that are citizens too
not a big deal and the kids are still doing better than before, no reason for the uproar
