Not when the only reason the Green Brigade are out is because the **** are, both bigot fans out for the sole intention of trouble.
What are you basing this on? It's possible for the Green Brigade/Celtic fans in general (UB/Rangers fans also) to have other interests outside of football, this isn't the first time they've been involved in antifa/pro refugee stuff. The both as bad as each other stuff is fine when that's clearly the case but today it obviously wasn't, one side happened to include a good amount of Celtic fans, the other probably contained a good amount of Rangers fans. Not everything is about football.
