Counterpoint, the people that strongly oppose agile practices the loudest have never managed a software project in their lives.

In your case, you've CHOSEN to ignore the scrum practices in favor of nose-to-the-grindstone death march. If your company says "we do scrum", that gives you and your team ammunition to say "no". Or in other words, poor planning on management's side does not constitute an emergency on yours.

Scrum practices, if done right, offer predictability. Management loves predictability. You should love predictability as well because it means you won't have to do overtime / stress.
