Are the TO's allowed to not allow certain people entry at their own discretion, or if they hold an official tournament are they compelled to let anybody enter except those on FFG's list? I think it should be the latter.
It seems odd that if you as a store owner bans a player for cheating or misbehaving at a MtG tournament are NOT allowed to keep him/her from entering an X-wing tournament.
The problem is you could have a TO who's just a bad person, maybe racist or homophobic or just for some other reason has it in for a given person and doesn't want to let them play. I think it would be right for FFG to say "if you're using our name, hosting an official tournament kit, then you let anybody enter who isn't on our ban list".
I agree, discrimination should be prevented when possible. But what if a store owner has a ban list of his own? I don't think FFG is capable of (or maybe even interested in) enforcing a limitation of store owners autonomy.
