It depends on how many people are left. You really cannot say unless you were in such dire consequences. There are too many factors to consider to determine whether you would stay within your own group or not, especially if all of your mates/friends/family are dead. You may have no other option but to join an out-group. People do dire things in the face of extreme circumstances. Going solo, you would almost inevitably die.
However, the reality is that in the face of a zombie apocalypse, many people would take the chance of joining an out-group in order to survive--not many would choose to go solo. Obviously, you're no different. Of course, you want to appear manly on getbig. However, in such extreme circumstances, you would surely join a group, especially if you needed food, water, shelter, or guns/ammo.
Nah, i don't care about that at all (appear manly lol), i'm too old and been through too much to care about appearance these days. (not in my 30s anymore)
Couldn't care less on how i appear these days.
I'd rather take my chances solo and probably die due to zombies than group up with some liberals or coloreds. Listening to that mumbo jumbo is prolonged torture.
I am not afraid of death, i've seen too much death in my life already and endured enough loss.
But if there is something i cannot stand , that's liberals cunnts and coloreds. Grouping with those would sooner or later push me over the edge and do a "Falling Down" on them.
Better to try stay alive as long as you can until you find some like-minded groups/individuals. If that doesn't work, so be it.
