CR used to be a tradition where arguments would split friendships irrevocably. One such led to the formation of the Imbas mailing list from the ashes of a debate on Nemeton-L. I joined the online CR community shortly after that, as memory serves. Since then, I've seen multiple iterations of arguments about everything from clergy within our tradition to three realms vs. four elements, the placement of the sacred cities, and on up to the latest row about male flametenders for Brigid.
The difference with the last argument is that nobody felt the need to flounce out of the forum it happened in to start their own little fiefdom. There are two different groups doing Brigid order building now, but that's a positive thing to my mind. There is a need for diversity if a tradition is to flourish. I've argued we're a living tradition and not an attempt to build a replica of a dead past before. That sort of thing only proves it to me.
The unfortunate truth is not everyone grows up. I've seen people who think it's 1991 in CR and they can act any way they please, only to be shocked to learn their tricks are getting so overused a five-year-old can see them coming. That sort causes schism and continues to do so. I'm at the point where if someone wants to encourage the children, they should sit at that table and quit acting like they're being grownups.
We still have our issues, blatant acts of denial, and petty gamesmanships. But I'm so relieved it's possible to sit down in even an electronic forum and not worry the next words out of my mouth are going to lead to yet another irrevocable blowup.
