Yes unfortunately you cannot protect group A from the actions of group B hermetically without hurting group B, if group A and group B interact.

Someone will be hurt, or by the actions of a member of the second group or by the societal actions to protect the second group.

I just wish the compromise was clear and we abandoned the kind of puritanical thinking that we "ought to protect group X" no matter what. We need to talk, qualitatively and quantitatively, about all the sides of the coin.
