Still don't agree that only home fans should be allowed to stand, that is segregation and it's not what our sport should be about.
I'm not sure but I don't think clubs have the power to make fans sit in seated areas so you could find away fans standing where seats are anyway.
The reason I raise this is because i've been to the Keepmoat and Bramall Lane to watch rugby matches and have been told by stewards that I was allowed to stand and when the home supporters complained because I was blocking their view from the bar the steward said I was entitled to stand (but not if it was a football match)
