I specifically say that simply doing something that's slightly different (eg engineering) doesn't make you a pick-me girl. A varied outlook doesn't make you a pick-me girl.
What does, is reinforcing sexist treatment of women, as in my first two examples. What does, is adopting so-called 'male traits' while at the same time loudly eschewing all things 'feminine'. Excusing that as 'just being themselves' let's them get away with it, and they should be called out like any other sexist. Just because they're women, doesn't mean it's ok.
When they behave like this, they literally are against us; that's the whole point of what they do.
