Thanks for this intelligent and insightful post.
A pair of testicles is not a prerequisite for announcing a sporting event or for performing most occupations. It's unfortunate there are a lot of men (and plenty of women as well) who feel threatened by successful women in traditionally male roles.
If the original poster didn't like the announcer and wanted to avoid the blowback he's deservedly received, he should've identified Mowins by name (instead of the "female announcer" label) and articulated some cogent reasons - - - that have nothing to do with gender - - why he believes she's no good. If he thinks she's terrible simply because she's a woman and sounds like a woman (12 year-old boys typically don't sound like men), then he's an idiot.
