I was reading a some blog comments at www.ajc.com and apparently Mandisa lost some support among gays for talking to much about God. Apparently Mandisa has stated that she is a big fan of Beth Morre the christian writer. Beth Moore on her website apparently has a link to an group that tries to help people come out of the gay lifestyle. Remember last week when Mandisa said something (before she started singing) that God can help you come out of any situation any lifestyle, etc... I don't know if thats why she lost but its possible.
I was thinking that she was referring to the lifestyle of overeating/obesity. She has clearly become comfortable in the skin she's in, which I think is wonderful. Her very strong faith has also given her much confidence to speak out. I applaud her!
