Silence does not imply consent.
Oh yes it does. Speaking out against something shows dissent. Silence implies consent!
Actually, yeah, it does. If you stand silent in the face of something that goes against your principles, then you are giving tacit approval to that thing; especially when you are directly affected by that thing. This is the case here. Toby Keith's name is hanging above a door that tells gun owners they're not wanted and he's been as quiet as a churchmouse about it.
