What an absolutely bizarre whataboutism, so vapid and self-evidently disingenuous that I can't believe I'm about to waste my time picking it apart, but here we go:

First of all, rescuing children from traumatically abusive environments is not the same as what the meat industry does to calves. Separation from parents is inherently traumatic itself, but that needs to be weighed against the degree of harm that the abusive parent might do, on a case-by-case basis.

Secondly, there are certainly cases of the government separating children from their parents that should be protested. Like when Texas defines transgender-affirming households to be committing child abuse and uses that as a reason to forcibly separate the child. Or when immigration control separates migrant children from their parents.

This might come as a shock to you, but it's possible to care about and advocate for more than one issue at a time. I don't know if your emotional capacity might be limited to just caring about one thing, but most people don't suffer from that limitation.
