Zampa Don't be ridiculous. Every single one I've encountered without fail was behaving appallingly. There were upwards of 200 on that site and I've since had the misfortune to encounter other groups bahaving in exactly the same way. So yes I'm generalising because out of all the travellers I have encountered 100% behaved like this.
I have also met lots of men. 0% were rapists (as far as I know) and I've met lots of black people and 0% of those were drug dealers (as far as i know) so what a stupid comparison.
People make judgements based on their own experience.
