Russia became completely isolated and their economy is taking hard. All in a matter of days. That's not "critique and public pressure" and usual diplomacy, those are concrete and coordinated actions that the world and NATO countries are using, but the fact that haven't been used in the same level in other instances is just because Russia is an adversary in the world stage. So, yeah, that they use usual diplomacy, critique and public pressure between them, means nothing now. And when we have other conflicts that are just as serious in other places of the world, and these same countries don't take the same action, it confirms that NATO countries act based on ideological and geopolitical goals, not because they are a force for good in the world, which is troublesome since those ideological and geopolitical goals aren't good by themselves just for being themselves, and countries can be decieved into taking action when the reasons and results will be fucked up. So that answers your question of why isn't good that NATO has those ideals as a principle to join. Have they sometimes taken actions that were correct ones? Sure, not everything is black or white. But that doesn't mean they're the beacon of justice, freedom and democracy they claim to be.
That sanction you mention proves my point. They sanction Erdogan because of buying weapons from an adversary. They can accept everything else, but the line is drawn at dealing with their rival. So no, the US doesn't care about the rest as long as it doesn't hurt them.
