Is there a lore reason why red and blu are fighting? Are they stupid?

Just share the land it's not that hard

tell that to the middle east

I was told by a drifter who's never lied to me before that at a peace summit between RED and BLU someone dared to let loose a huge gaping yawn during a heartfelt speech on why peace was important.

Since that day, it's all payloads, seals, sandviches and cosmetic updates.

[Spartykins]

two brothers running separate companies that hate each other so much they are trying to forcibly take territory from the other using mercenaries

as for why it's allowed to happen? Idk ig in lore the conflicts are contained enough where it's not that disruptive to the local population plus the conflict generates a lot of income for various groups that supply arms to both teams

There comics on TF2 official website you can read if you want more lore

TF2 is full of lore. Read the comics.
They fight because Blutarch and Redtarch wanted to have a bet who would live longer.

Because Red is the wrong colour and blu don't like people of the wrong colour

Love how nobody got the reference but it is what it is.

Look up on TF2's offical website and you'll find a comics tab underneath it.
There you'll find a whole assortments of comics you can read to get a glimpse of what is the in lore explanation of why Red and Blu are fighting against each other. It's a big read in total so unless you have a disability that prevents you from reading more than a thousand words... Go watch a Youtube video that summarizes it all instead you .

As in game lore? Non canon during casual match fights (You seriously gonna believe that Brazil is in the badlands?). Only MVM has some ties with the comics (Mostly the vicious cycle of a endless loop stalemate fighting).
The comics say that they are separate continuity but I find that BS due to the amount of effort put into them and it's the closest thing we'll ever get for TF2 to have an actual story.

L for Hale though. He lost his girlfriend to his arch nemesis. And the Headless horseman in game can two shot his ass to the shadow realm.
