The LCMS has always had infighting. I think it is what old Lutherans do for fun. The fighting since 2000 has been about the Synod leaders and their approach to thing like 911.
WELS has its own problems also.
LCMS (I was a convention delegate) is divided along the lines of doctrine and practice (modern marketing schemes substituted for mission and worship). Many think that the division is over doctrine and mission but...they're just wrong AFAIC.
The feminazi voices are not as loud as they think themsleves to be.
WELS and ELS are the most likely refuge of many who will leave (my count shows about 1/3 of the 6200 "congregations") but both WELS and ELS have a an active contingent of those who prefer a "business model" approach to church as well as some trouble with their teachings regarding the Office of Holy Ministry (overly broad in respect to the practice of laymen and overly narrow in respect to the clergy themselves).
Well, as long as there's food!
Apparently, they are keeping gay acceptance at bay.
This was an interesting site on LCMS when I was searching: http://www.reclaimingwalther.org/
LOL - I think ALL the synods have had infighting. Have certainly seen my fair share of it! :)
