If you really use that as a argument, then how about planning to sleep or not to sleep with someone BEFORE going to the bar
? And how is it different?
I think the analogy is poor because in the drunk driving situation, someone has the ability to make it extremely hard for themselves to drive home after drinking. Ie, they could take a taxi from home to the bar, then from the bar to home. In this situation there is virtually a 0% chance that they will be driving drunk.
Let's say this same person gets extremely drunk and is persuaded to go home with a rich and famous athlete. There is probably no way this could have been "planned for" in the same way that the transportation arrangements could have been planned for. It is much more likely that someone could be convinced to go home with someone from the bar than it is for someone to make proper transportation arrangements, and somehow still manage to drive home drunk. Just by being drunk and in a crowded setting, you make it more likely that you may be targeted for sex and by being intoxicated, you make yourself more vulnerable to certain situations. I'm not trying to blame the victim here, I believe I am just stating the fact that you have more than a 0% chance of being taken advantage of in a bar under the influence of alcohol.
If you plan accordingly to make it impossible/unreasonable to drive yourself home, then it's just not going to happen.
Not trying to start a fight or anything, just want to make my argument clear.
Leaving car at home: 0% chance you will be driving your car home. It's impossible.
Simply being intoxicated at a bar: more than a 0% chance that you might be persuaded into leaving with someone that you wouldn't otherwise leave with. It's possible.
