I'm what you could call the new breed of away fan. Mid 20's and now luckily able to afford more away days. I understand what your saying but I honestly believe the idiots kicking off are a very small minority. In fact, the only blue on blue trouble I have seen as been guys well into their 40's.
The beer throwing has been going on since I remember going City, but yeah if your sober I suppose it will piss you off getting covered in lager. But been happening at big games for years. Young lads ave always been rowdy at games, it's just now older people tend to make up the most of the away support. I'm not condoning the behaviour or Munich chants at all, but again these have been going on for years. Thankfully the Munich chants are dying out, and I believe they are at an all time low. Unfortunately pissed up people at football games are going to act like dicks. Again I have seen plenty of older blue doing exactly the same. Idiots are idiots.
I do sympathise with the older generation not wanting to have this rowdiness around them, and they are well within their rights. They put the miles and years in supporting well before us. But please don't tar all young lads supporting City away at football as thugs.
