It's worth reading Macklemore's full letter regarding how Robert Kraft, owner of Gillette Stadium, pressured Ed Sheeran to cancel Macklemore, and how Sheeran caved to this pressure, despite 1) his decade-long friendship with Macklemore, and 2) how Sheeran had no problem eschewing "neutrality" when it came to Ukraine.
What this shows is exactly what @EliClifton and Ian Lustick write about in their new book "Israel's Lobby: America in the Grip of a Foreign Power."
It's no longer just about how Israel or pro-Israeli elements push US foreign policy in a direction that undermines US national security (such as starting a disastrous war with Iran).
It's now also about how these elements constitute a direct threat to the freedom of speech of ordinary Americans, and as a result, a threat to American democracy.
