You can do both, it's not mutually exclusive.

On this case, I don't think your Law requires children to be imprisoned away from their parents, nor that it requires that illegal immigrants be imprisoned instead of deported. If that is really the case, the blame falls entirely on the people enforcing it.

When my parents went to jail, I didnt go with them. There are obvious logical considerations both sides are ignoring here. While seperation is clearly not good, the alternatives may be worse in some cases, as they were mine.

This is whataboutism. You can and you should engage politically against every level of institutions who hurt moral principles you believe in.

Engaging politically is not virtue signaling.

It is to nihilists. And also to those who seek to disarm others and render them unable to act for their beliefs.

You see, then, the dire trouble we are in as a polity.

The entire concept of engaging against institutions that one feels are immoral is "being an asshole"? Or just this one? What principles are such a broad, hateful sentiment based on?
