I agree with you, some of the women you see here are just an embarrassement. But do you honestly think it's better in other cities? I've travelled around Europe and have found that the way they drink is different to us, they stay out until much, much later.
In places like Spain, Italy, France etc. the girls make absolutely no effort when they go out. You don't see girls in nice dresses or high heels like you do here, so I think this makes it worse when you see a pissed girl here to be honest. Appearance does make a difference, and seeing a drunk girl in trainers and baggy jeans stumbling around somewhere in Spain somehow doesn't seem as bad as a girl in five inch heels and a bodycon dress here.
And when I went to Poland, I personally saw many more pissed and easy women there than I have seen in England. Even my male friends who have been say that whilst girls here look like they might be 'easy' because they make an effort to go out, girls in countries like Poland and Russia actually are easier. Two of my friends who don't know each other went on two seperate occasions and one got head off a girl after buying her one drink, and one got a shag.
I do find that the girls in England have an aggression problem though. I don't understand where this has come from but I've seen this so much, girls starting fights on other girls AND guys when drunk. It's insane!
I think the problem with a lot of girls here is that they like to act like they're on the same level as lads. Match them drink for drink, be as loud and have as much banter. It doesn't work, even physically. A guy drinking 8 pints will get him pretty tipsy, a girl will be pissed. I don't personally understand this need to prove things like 'I can drink so much!' to a man and then ending up walking through the centre of town, holding your shoes and covered in puke.
Not speaking from experience there, thankfully!!
