Isn't the 'finger sign' as called by KS really a universal language?
I can go anywhere in the world walk up to any adult, give them the 'finger sign' and they will know exactly what I am saying. I don't need to know ASL, they don't need to know ASL.
What other hand sign is so universally understood?
This has nothing to do with ASL and everything to do with the Watchtower organization.
