Placing moral or ethical judgement on an entire group based on the actions of a few is the most violent form of communication, and the basis for perpetual physical violence.
Ethically wrong? Sure, I can go there.
The most violent form of communication? In light of what Hamas just did, that seems like an absurd statement.
As I said in a previous post, if there's ever going to be peace, some of those who have killed in the past are going to have to go unpunished, and some of those who have died in the past are going to have to go unavenged. You're going to have to sell that to at least one side, and probably both. That's the only way out of the cycle of violence.
