I respect your view but I don't share it. I'm never close enough to opposition fans for them to hear anything I might say or vice-versa. They add absolutely nothing to the occasion for me; our team and our fans do that perfectly well.
Do they really NEED away fans for the atmosphere they create? Personally, I couldn't care less if there are away fans there or not, and I don't believe they add anything to the atmosphere.
We create our atmosphere, good or bad, for our team.
