I still say ban the troublemakerls
Troublemakers of all kinds should be banned from sporting events, protest marches, anywhere they are a potential danger to others.
However, that does not mean that all the rival team's supporters are "thugs", does it.
Of course, known troublemakers should not be allowed near the ground.
However, tarnishing them all with the same brush is very wrong.
Or are you saying they would be in danger from other elements, our own troublemakers here in the UK? If so, those troublemakers need to be dealt with so that everyone can go about their business peacefully on our streets.
