Absolutely, one should criticize the government - all the layers of it. Trump is one (temporary) layer.
And of course, we are all free as individuals to focus where we want to focus.
I wanted you - my Nostr friend - to know that from my perspective as someone in the US, Reich is not a good source of information. From what I can see, he is more interested in stirring up partisan outrage than he is in the actual issues that he claims to champion (freedom of speech). But admittedly I don't know his work well - I've only seen some recent snippets - so it's time for me to sign off on this thread!
Best to you!
