Your comment just isn't very constructive. Everyone knows that driving drunk is moral reprehensible. That's not the point.
I'm sorry for your loss but I could just as easily say something along the lines of
"Driving in general is not an excuse. People downvoting me obviously haven't had anyone close killed by a distracted driver. Simple solution: don't be distracted and drive."
You're not wrong, but as long as we continue to have an attitude of "drunk driving is just wrong so we shouldn't do anything because people who drive drunk are simply bad people" we will never create a proper solution and people will continue to die needlessly.
It's not an excuse, but understanding people's impetuses (that are more common than you probably believe) will help us in creating solutions and getting rid of this problem once and for all.
The post I replied to sounded like it tried to justify it, like there was no other choice than to drive drunk. I also don't agree with you at all. You speak like it's some kind of technical problem that needs to be disrupted. If you drink and drive you're messed up and have big issues. Of course we should try to find ways to reduce it but you can never blame the system.
I'm not saying you don't have big issues if you drive drunk but that statement is obvious and does nothing to solve the problem. No one is going to start accepting drunk drivers as good people. But maybe we can understand why people drive drunk and can fix that underlying cause. After all, all I want is for fewer people to drive drunk.
