"We can only indulge in such a guilt free way because we don't see how the sausage is made."

That might be for some people. There are many that would have no guilt. As you point out, some people know what is in a chicken nugget (chicken) but eat it anyways. This path might slightly reduce the number of omnivores, but I doubt it would have a serious impact overall. Like any reduction in consumption from them would just lead to a lower price and increased demand either domestically or internationally.
