Of course you're right in a logical or philosophical sense, but in a political sense it certainly does. If the emails were fake, it would be politically insane

Of course you're right in a logical or philosophical sense, but in a political sense it certainly does. If the emails were fake, it would be politically insane not to say so. The Biden campaign can easily find this out from Hunter, so the fact that they haven't said it means either that (1) the emails are authentic (though they may still have been altered), or (2) something else is going on that we don't know about and is unusual.
