In some cases “not all men” is used to shut down the woman who is speaking. It’s like saying since not all men are like the man described in your experience, your experience doesn’t matter. In that case, “not all men” is a phrase I wouldn’t use. However, when the individual extrapolates his/her experience to the men in the industry as a whole, comprising of millions of different people, I think “not all men” or “not everyone in this industry” is a perfectly valid response.
