when the poster says you might not check for consent, get into a fight, all these are very specific precise issues that can happen if you are drunk.
With the walking alone, nothing is specific. It's like ANY issue that can happen when you are walking alone drunk(!!!) are then down to you because you shouldnt have done that.
So yes it can be slipping in ice, falling into the river. It's also being robbed, raped, etc etc...
Whilst you can argue that falling into the river would be your entire responsibility, I have a massive issue with the fact that all the others things that might happen to you (such as being assaulted) is also somehow becoming your responsibility. Because you were drunk.
Walking alone Is NOT in any shape or form an issue, drunk or not.
Going for a walk near a river when you are unsteady is.
Walking on icy pavement when you are unsteady again is.
Both of those problems can happen when you are not drunk (but unsteady for whatever reason, e.g. Illness or plain exhaustion) or if you are drunk but with other people (will they jump in the icy cold water to rescue you if you fall in the river do you think?)
The advice is too wide and unprecise to have any meaning IMO.
It's a shame because all the other commentsand esp the one about consent are vERY good IMO.
