why does this list break DKIM when forwarding?

From the Gmail headers your email :

 Authentication-Results: mx.google.com;
       spf=neutral (google.com: nanog-bounces+scott=example.com () nanog org does not designate permitted sender 
hosts) smtp.mail=nanog-bounces+scott=example.com () nanog org;
       dkim=pass header.i=@linkedin.com;
       dmarc=pass (p=REJECT dis=NONE) header.from=linkedin.com

Sure as long as I make sure my post is plain text only which you know is not anymore a standard on many email clients 
(and not configureable on many mobile mail clients).

So if this list stops to strip the HTML mime part it will pass DMARC in all cases.
