Bright colors in slides, whether pink, blue, purple, or orange, is distracting in a presentation. It takes attention off the information being presented and puts it on the design choices.

Visual ticks - wringing your hands, messing with your hair, licking your lips - make you appear less confident, and has nothing to do with gender.

The vocal tick - making every sentence sound like a question - is distracting no matter who presents it.

These aren't gender specific criticisms in any way. Regardless, unless you're addressing a gender specific topic, why bring your gender into it in the first place? I'm interested not in the person presenting about algorithms, but the algorithms themselves.

A man would be rightly chastised for presenting a de-duplicaton talk with bright pastel blue slides, pictures of beer, and rubbing his forehead while presenting, why shouldn't a woman?
