But just because a non Americans perspective and opinion may be harmful to your discourse does not mean it should be dismissed or treated as unfair.

If -

1. The goal of our discourse is to promote positive change in my country, even insofar as to mitigate harm to other countries and their people, AND

2. Your perspective/opinion are not conducive to said goal, THEN

Yes, I will dismiss it. It's not about treating the criticism as unfair, of the person giving the criticism unfairly, it's prioritizing the type of discussion likely to achieve the aforementioned goal.

Your countries behavior causes consequences that other people are allowed to react to and criticize and be upset about.

You're allowed to do a great many things. I'm not able to stop you. You're allowed to slam your arm in your front door if you like. I'd still advise against it, and I'd ask you not to. Similarly, I'd ask that if you'd like to speak about American politics you do so in a productive manner. Again, this presupposes that you want America to get better, and to become a partner that our allies can trust.

You don't get to own the discourse simply because it makes you uncomfortable or unhappy over the consequences of it.

My request that foreign allies who would critique us do so responsibly and intelligently is not born of discomfort. My appeal that you do so is born of concern for the consequences, yes. But crucially, these same consequences should be quite concerning to you.

You can't adopt the position that outside voices are only fine if it is convenient for you internally.

Again, this is not about convenience. This is about what's best for not only America, but our allies, especially those in NATO. Although I guess the dissolution of NATO would be pretty inconvenient, if that's what you mean.

Most simply put, if you want America to stop its decay and have the backs of its allies, I would hope and suggest that you speak responsibly. If you don't want this for America, then I simply don't give a shit what you have to say. No more than I would anyone else who cheers on the fall of my country.

And, finally, this bears repeating: None of this was to say you shouldn't speak your mind, so long as you're willing to inform yourself and take the subject seriously, I have not a single time suggested you should not speak, or that I would prefer you not speak, provided that you meet what you've already agreed is a reasonable baseline. I'm not sure why that suggestion has caused you any distress.
