+1 for State of the Union and Sentry the Defiant. I also see your Waking the Demon and raise you one You want a Battle? (Here’s a War). I don’t know if we’re all against Anti-flag with Justin Sane being a trash human, but their catalogue is still good for this situation.

Not really a work around, but you could get a VOIP number from MySudo or Hushed or a similar service and use that to sign up for Signal. Might at least be more private if you go about it with like a prepaid card and temp email or something.
