> there is no nuanced or intelligent position that defends the assertion that you aren't responsible for your own actions

Such a position is a longstanding feature of law.

I get that some people don't want these principles to exist and would prefer personal liability in everything, but I would suggest that these people be very careful what they wish for.

I get that a lot of people want to substitute law for morality because are incapable or unwilling to understand the critical distinction between the two.

The only distinction is that with law, you can actually hold people responsible for their actions in a way that matters.
