Its the bolded part that bothers me. Flip the scenario around, put Rick's disc there and Paul says its in and Rick says its out. because we have a culture in our sport of trying to "get your strokes wherever you can", or try not to take any penalty strokes if you can argue your way out of it, as opposed to other sports that play from the spirit of the game, call their own violations on themselves, and things like that.
To be clear, I'm not really arguing that players should decide based on emotion rather than objective observation. My point is that it if you feel you are correct (regardless of which side you fall and how you may benefit from the call), don't back down. Nothing worse, IMO, than thinking a disc is OB or in-bounds and not voicing that opinion even if you're over-ruled. That goes whether it's your disc or not. Rick was right to call it OB if he thought it was OB, just as Paul was correct to argue he wasn't if he didn't think he was. Reverse the positions and I feel the same way.
Nothing to do with gaming opponents or stealing strokes or whatever you want to call it. Call it like you see it and stand by your call. If that means 5 minutes of deliberations before the group settles on provisionals, so be it.
