Is it normal that I hate English people?

I have met some nice English people when I was there, there are good people everywhere. But in some parts of London, and in the more up north of England is where I found more of the "fuck manners and respect" types of people. Most of the northern English seemed to make up their minds not to accept me as soon as they saw I'm American. And when I went to the Club 18-30 trips to Maguluf and to Tenerife, there were a lot of northern English there and some of them were downright hateful towards me. Most of them, including the Club 18-30 reps, and just about all the northern English vacationing there thought that the only thing that mattered was getting drunk and laid. I tried drinking and having fun with them and they still totally alienated me, those northern English hate Americans for some reason.
Now the nice English people I met were mostly southerners , except for in the shithole parts of London, the southern English were where there were nicer people.
