The promoter of the event should have made sure that all promotional materials were approved as per the contract they signed.
What if the "promoter of the event" whom did not gain prior approval (which is the actionable offense per the contract, no?) was NOT the party that signed?
Then what?
Contracts are between the signatories, are they not?
Time for you to start answering questions, bucko!
If it be found that it is some sort of "guilt by association" of another entities actions which are being transferred over to the signatory wishing to show the film, then the argument or accusation of censorship looks valid to me.
Frankly, I don't care much for what you think, since you have displayed for me here already, the way you think.
But go ahead, knock yourself out...blather on with more ridiculous justification. You can have the last word. I'll not be responding, if you simply give more of the same as you have previously, continuing to duck any and all related issues concerning the underlying issues and ideas touched upon in the article which is at this thread's heading.
On the other hand, if you wished to discuss this more as an adult, then by all means...
It is your choice.
