I have an opinion about this, for what it is worth.
The way I see it, Fluther clearly has a predominant culture, with an established set of principles that determine whether or not you are a “true” Jelly, or a bothersome pretender, a troll, or worse.
Adhering to these principles by and large seems to mean that you are politically correct, that you think global warming would never have happened if humans had simply remained speechless primates, that you think that wealth is a zero sum game, that you think the current president is not just another self-aggrandizing politician, that people of the Christian faith are sort of provincial morons (other faith based religions seem to be OK however) etc. etc.
It also means that you should ask questions because you need a particular answer. I believe a lot of people think it is mildly to severely inappropriate to ask questions that challenge the doctrine, or to simply to see how people will answer, and to get a lively debate going in a thread.
This is what I think they mean by “stirring the pot”.
I used to love to “stir the pot”. The problem is, as time has gone by, all the people who enjoy stirring the pot, or who got a kick out those who do, have quit or gone missing. Too much of what is left is the process of reinforcing group-think, dream interpretation, and how deal with such abominations as rude people and disapproving parents. Not as much fun as it used to be, in my opinion.
And the sun will come up tomorrow.
