100% agree. Me presenting it as a choice by a single Commissar for War is more tongue-in-cheek. The answer whether or we should do it is contextual but my point is that there are clear cases which I can imagine in which drafting would be clearly justified, even if of only certain groups.
But responding to a question of whether or not we should do something by saying it would be decided democratically is evading the actual question of what you would put forward or support as appropriate policy in such a scenario. If everyone one responded that way then nothing would be decided.
