"Did I ever hear him make remarks that could be considered controversial while I sat in church? Yes. Did I strongly disagree with many of his political views? Absolutely -- just as I'm sure many of you have heard remarks from your pastors, priests or rabbis with which you strongly disagreed."  

Disagreed?  Maybe, but I've never heard one of my rabbis say anything remotely comparable to what Wright said, and if I did, I can assure you I'd be up and out of that service--and that temple--in a jiff.  Being controversial is one thing--spewing hate and misinformation is another.
