This is typically how it goes:
Lutherans (at least the ones who care), try painstakingly to distance themselves from anything that smells Reformed. Example: http://cyberbrethren.com/2012/12/12/brace-yourselves-grace-is-not-irresistible/
The Reformed (at least the ones who care), try painstakingly to show how much we have in common in Lutherans, and how we need to better understand each other: http://heidelblog.net/2012/12/resources-on-understanding-the-differences-between-the-lutheran-and-reformed-traditions/
This sort of reminds me of my first Rubik's Cube. I think I eventually gave up trying to make it the same color on each side. Once I would get one side to be all the same color, the other sides would cease being all the same color.
