Exhausting, really. More than tired

I hate when something happens, and I feel like I can't write about it here. It's the worst kind of censorship. The censorship of Who Might Read This.
Did y'all see that episode of Friends where Joey, Chandler, Monica and Rachel decide to go on a trip and not invite Ross and Phoebe? You see, Chandler decided that Ross and Phoebe weren't as much fun to have around anymore, and decided they should be excluded from the trip. Joey, Monica and Rachel didn't stand up for Ross and Phoebe, thereby sanctioning the excommunication with their inaction. The whole thing got even crazier when no one talked about how shitty that move was, and the entire episode was a series of passive aggressive "polite interactions."
Sounds painful, right? I mean, we're looking at a group of friends who have shared everything, had a great time together, been each others' rocks, and would literally travel across country to spend time with each other. So why does Chandler get to decide that Ross and Phoebe shouldn't be included? Why won't anyone else say anything? Why has this situation, in the show (of course), devolved into people acting like high school kids with their super-exclusive clique when really, they're all almost middle age and no one should be allowed to dictate which friends should be allowed to participate in all-group activities based on that one person's perception of their fun barometer? Isn't there room for everybody, whether Chandler likes it or not?
The whole thing just makes me tired.
