This is the silliest debate ever. WaPo is even getting involved.
"Should Americans hug or not?"
All you do is ask.
"Do you feel comfortable with hugs?"
I do this. (And confirm regularly, in case they change.) As a result, some people I hug as a greeting, and some I do not.
We should not stop hugging those who want hugs. And we should not start hugging those who do not.
