Again, the problem you're missing that in some groups
this isn't disruptive. Its what
they do during play. Note upthread
@TwoSix mentioned that's like 80% of his game play. Even the spotlight hogs are often just something that happens some of the time that other players just take as part of the gig.
Good morning, BTW.

I'm not the one with a problem. Look upthread. My games of friends, acquaintances and allies are never ruined by disruptive players. I've never experienced the problems others here have described with RP that goes out of control.
A lot of this stuff isn't perceived as bad behavior.
I know. I've followed the threads and the endless semantic debates about it.
Bad behavior is bad behavior, IMO. Trying to spin bad behavior into something else is how some people rationalize it. That's what I've been seeing -- a lot of rationalizing. It's like when a parent rationalizes their child's bad behavior because they lost control of them a long time ago. Appeasement without consequence leads to chaos and a lack of respect around the table. Pretty soon the child in the parenting example is calling their mom by her first name and cursing her out. Mom: "Timmy, please clean your room today." Timmy: "No, Jane, I won't do that. Shut the $%@# up about it." If Timmy is never made to experience a negative consequence for that behavior, Timmy will get used to it.
I'm going to mention again that at least the first part of that is not a given in any way. There are plenty of games where the GM "controlling the table" is not a priority and they still get by fine. Even if you insist on doing that at your table, you've really got to get over assuming its a law of nature.
You're missing the thread here. The recent back-and-forth discussion in this thread, prior to me engaging in it, was about RP and players becoming disruptive for hours. That was the premise. Read upthread. I didn't start out by calling it "disruptive." I responded to someone else's use of the term upthread. What if a DM has a game planned, but their players choose to RP for hours doing disruptive nonsense instead?
In that scenario, I think the issue was that the DM either lost, or never had, the respect of the players, and therefore lacked the control necessary to corral them. That doesn't happen at my tables. Period. Never. Does not happen. Take from that what you will.
Again, leaping to conclusions that playing with strangers will automatically lead to problems. Seriously, it just doesn't follow. Frankly, I've seen as much problems from games with people playing with friends and family as I ever have with random mixes.
This should not need to be said, but here we go: there will always be exceptions, as there are always exceptions to everything in life. That there are exceptions, though, should not always -- always -- have to be highlighted in every post, unless we're having a pedantic debate instead of a reasonable one.
I will reiterate my opinion that it's easier, barring rare exceptions (if you must have them), to maintain respect and control around a table when you DM for friends than when you DM for complete strangers. That is irrefutable, IMO.
