The only one having major anger issues right now is you.
I think you have totally crossed the line with this one.
I can tell you that FH is not out to hurt anyone, I know his character. I also know that FIB posted his email to get an opinion, NOT to get anyone's bowels in an uproar.
And I highly doubt that FIB has hired you to be his mouthpiece.
And in answer to your question, YES I do think it is appropriate. It is his opinion. He wasn't out to hurt FIB, and he sent a private email, and didn't post his opinion on the DB board.
There can be no testimony without a test. I am praying to go through this test and come out the other end with a new and better marriage then before.
