I also realized that I need to start practicing what I preach.  I regularly tell guys here to ignore the negativity, something I failed at miserably all day long.  It just isn't that easy and I won't be so glib in the future. 

Tom-
Don't beat yourself up.  You are only human and as others have mentioned our families know how to push our buttons.  I like to say that there is no such thing as the perfect family.  Everyone has dysfunction including MINE!  First time my Mom saw me with this beard her first words were "I hate it'.  My entire family including extended family are clean shaven.  I just look at it that I have to be the trailblazer.  It's great your wife and daughter love your beard.  You along with your wife are all that matters.  Lastly, you ARE a role model on this board as you have helped so many of us.  Be yourself and GROW ON.... 

BTW, your braids are kick ass!
