Merely repeating what I said before: they seemed to be going about perfectly happily and offending no one ... until they got to the stadium, where as we know fans have also been prevented from wearing rainbow colours. This ridiculous restriction has now been lifted.
It strikes me more as heavy handed officialdom more than anything else. There are plenty of "Crusaders" themes, especially in sport (and indeed Saracens) and I am pretty sure there is next to no offence caused by any of it. Qatar is not exactly Iran, either.
