Nah, i know mate. Just interested in your research as I did something similar at uni for my dissertation.
50% sounds high to me but even of that's right, that's half that are alright!
What was your outcome for your dissertation mate?
I have lived overseas in loads of different places for beards mate, so I base my perception on watching loads of England games in different bars with a large cross section of the England supporting public. Of which the majority were bells.
And you're spot on, I should be commending the other half who are sound and not racist at all.
