Seems more like saying "Let's get a bunch of tea drinkers together, who all drink tea for different reasons, and different types of tea, to discuss tea", which sounds like a great thing for a bunch of people interested in tea.
Maybe the fact that there are many split communities is even evidence that a conference would be beneficial. Get some cross pollination of ideas going on.
It's like saying, "Let's get everyone who speaks English speakers together to agree on our favorite tea."
