He intentionally said YOU and not SOCIETY, because if it's ME setting the standards, that's easy to argue against. If it's SOCIETY setting the standards, that's much more difficult to argue against.
If I hire hitmen to do my dirty work, am I not responsible for the death of my neighbor? I suppose technically speaking that'd be false, but still ugly (I didn't "pull the trigger" personally). If you use the voting mechanism to achieve legislation, you have a difficult time determining who the "hitmen" were. It's all well hidden and abstracted within the mechanism of statism.
