Why do we have to remove YEC from the movement?

I'm trying to find the coherent fault line here that we've all been picking at these last fews days.

Incel versus Sex-Haver

Hobby enthusiast versus anti-hobby enthusiast

Those who believe in YEC versus those who don't.

These are all sitting over the eternal Christian/anti-Christian fault that zigzags all over these other positions.

Is it just that we've grown tired of putting aside daily grievances and petty rivalries? We have no enemies at hand to dig into and so we dig into each other? Our movement is too big perhaps and we need to purge the weirdos? COVID is over and Trump might return so we've got to clamp down on the schizos?

Are we hoping to make the ever fantasized turn from outsider movement to respectable movement?
