I do agree, but that's not what you wrote before. You wrote that "all humans should have the same protections against their rights being violated", which implies you think everyone should have the same rights. This clearly doesn't make sense, as I pointed out about voting rights. The bottom line is, not everyone has the same rights. Citizens of any country have more rights than non-citizens; there's nothing abnormal about this. You can argue that certain rights should extend to everyone (and I would agree), but this argument seems to have some disagreement about whether unreasonable-search-and-seizure is a right that should only be afforded to citizens or not, and I'm just pointing out that non-citizens don't get all the same rights as citizens.

Good news: none of the Bill of Rights are limited to citizens, and most are indeed broadly worded so that citizenship status is not a threshold requirement for the right to apply.
