soft or hard.
there are scenario's of staying as one chain (just orphan drama and being either small drama or mega clusterf*ck of orphans before settling down to one chain) dependant on % of majority..

but in both soft or hard a second chain can be produced. but this involves intentionally ignoring consensus orphaning mechanism.. in laymens: not connecting to opposing nodes to see their different rules/chain, to then build own chain without protocol arguing(orphaning)

all the reddit doomsdays FUD is about trying to only mention softs best case, and hards worse case.
but never the other way around because then people will wise up to knowing that bitcoins consensus orphaning mechanism is a good thing and that doing things as a hard consensus is a good thing.
