The comparison to deadly force.... seems hyperbolic. No one is in mortal peril. I would have voted you up without that. Those kind of statements make it impossible to have/take discussions like this seriously.
On the other point, I'm not convinced that supporting better fair use laws is enough on its own. An equitable compromise between two parties with fundamentally opposing interests can rarely be reached if there is a deep asymmetry in terms of their ability to just take what they want and run. Maybe, if comparison to anything involving murder is going too far for you, we can instead make one to (ironically enough) stealing: if the local group of school bullies keeps dragging you into dark alleyways and taking your lunch money, will you also support better rights to keep your lunch money but think it is going too far to demand that they be put in detention, because you see a pretty good argument why they should have a right to free movement?
The MPAA is not actively attacking you. They’re putting conditions on how you can view their content.
The current state of affairs is that it's not just legal to use DRM, it's illegal (DMCA) to try and break a DRM scheme, _even if you do so in order to exercise your legally guaranteed fair use rights_.
It seems to me that there should be some sort of sort of moral right to self-defense that applies here: just like society/the law recognises that it is morally acceptable to use deadly force to defend yourself from someone who is trying to murder you (even if it wouldn't be otherwise), we can recognise that it is morally acceptable to use the legal equivalent of deadly force (ban DRM, make it illegal for them to enforce their right to protect their content) in self-defense (against them using DRM to make it illegal for you to enforce your right to fair use).
More bluntly: Content creators, with their support of the DMCA, have proven that they have no concern for my rights or freedoms. What standing do they have to expect me to have any for theirs?
