A country isn’t really like your house though, is it?

Germany could probably tell Google not to host any videos from the opposition political party under penalty of fine or expulsion. Hopefully we agree that that would be bad?

Germany could also force all food establishments to add a little bit of poison to the dishes. Would that be an argument against government regulating food preparation standards?

We can agree that bad things are bad, but that doesn’t really gives us much insight.

But Germany can't do that because it would be against Germany's constitution.

It's a hypothetical. A Constitution can be amended or ignored, can't it? My point is that a country is not your house. And citizens are not visitors. It's the wrong analogy and leads to bad conclusions.

s/can't/probably wouldn't/

It is entirely possible for countries to do things which are against their constitution.

You know that Germany does actually outlaw promotion of certain political parties, right? Hopefully you agree German law is bad or you're disagreeing with yourself.
