Right, vicariously, an Us of unknown origin that come to the earth in search of a human host. Your words.
Nonsense.
I am one person with one body and one mind with one consciousness, soul, that I alone possess. When I speak I think the thoughts form the words and express them. There is no Us speaking through me. Your Us, as clever as it may be, has absolutely no place in me.
A person that abdicates possession of their own soul is the only person vulnerable to intrusion of such a malevolent self-negating entity, an Us, like a crowd of homeless people taking over and moving into an abandoned building that come from God only knows where.
