I think free speech is important, and she has every right to express her opinion. However, I think she should be less black and white about it. Someone who has influence / good media coverage should not just express their own opinion without some form of justification / conclusion. (After all what they say does have the potential to cause some uproar or upset.)
For people to have a slightest chance of understanding her hymn sheet, then her reasoning behind her opinion would be helpful.
I see no clear meaning behind her opinion, so its not worth much thought. As far as I am concerned she needs to get out into the wider community and expand her own very limited experiences of the homosexual world. It is my "opinion" that for a supposedly educated woman, she is blinded by her own inexperience. Does that not make her look the fool?
