I think a very important observation in all this is that there are non-gunners and there are anti-gunners.
We probably stand a huge chance of winning the hearts and minds of the non-gunners. Even if they don't become gunners. They might come to realize "Gee, my neighbor Craig is a gunner and he's a good guy".
We'll probably never convert many anti-gunners. But if we're not careful, we might convert some non-gunners into anti-gunners.
