Shaykh Hamza and Imam Zaid both spoke out in speech and in writings on the oppression and slaughter in Gaza which might not have reached YouTube yet. They even wrote moving poetry on the subject some of which you can find on Imam Zaid's personal website. Do a search for Gaza In the Hangman's Rope. The source material for this particular video was recorded a year ago in response to a particular situation but the advice is universal.
I see your point. Perhaps it would be best to address this question to Shaykh Nuh through his website for clarification and elaboration. Let us know when you receive a response.
