The Wells Fargo Center’s event staff is responsible for the security and comfort of all guests at arena events, including 76ers games. At last evening’s game, following multiple complaints from guests and verbal confrontations with others in attendance, two individuals were warned by Wells Fargo Center staff about their continuing disruption of the fan experience. Ultimately, the decision was made by Wells Fargo Center personnel to remove the guests from the premises, which was accomplished without incident.
Nonetheless, it doesn't look good in the wake of the recent China censorship scandal
Very rarely does a venue make a decision like this. The team leases the arena for the event, the venue does what the team wants.
If "verbal confrontation" were a blanket policy of the venue, then it could never hold another rock concert, monster truck rally, or other high-energy event.
This sounds more like, "We didn't throw anyone out, our hired goons did. We're clean!"
I don't actually have a big problem with this. The issue with punishing people for their tweets or comments about Hong Kong is that you are taking action against them for an opinion they have. In this case, they are just preventing people from expressing their opinion in a privately owned place. Now I would prefer that the fans not be ejected, but I also think it isn't that terrible to prevent people from putting up political banners in a televised arena. It also depends how consistently this is applied - would they also eject someone for holding a sign supporting Trump?
Unless is extremely typical of what you normally see at a game, you're not going to be allowed to show it.
