I do get what you're saying, but the comments were in line with other comments on the show ie the regulars are old, fat etc, the remarks are quite judgemental and condescending. The remarks I seen about Defoy were pretty harmless, she's very attractive, I wish she was on tv etc.
I think you're being overly sensitive. I doubt she'd be offended if someone had said "I don't think you're right for OTB, but you looked great."
