By the end of this year or early next year the leaders of 4thgen will start pulling away from the rest of the pack. Stans from unsuccessful groups will start to regret backing the wrong group and jump to the successful ones.
You can imagine a situation where a group you stan becomes a clear leader and the fandom grows and some of that growth will come from the very people you argue with on a daily basis on this and other platforms. ofc they'll be sneaky about it (using anons or making new accounts etc.). I doubt they'd publicly admit to being a hypocrite.
Wil it bother you or not?
