Okay let's play this game. Let's accept that women are indeed more emotional creatures.
(So tempted to get all sarky with "wide-eyed" and "fragile" but onwards.)
Now what's wrong with being emotional? Even in environments such as tech, this is a necessity. Ultimately people use tech, so damn right we need to be emotional about it.
'Emotional fits' though uncomfortable to watch don't actually occur often, but when it does, it is usually grounded in a very good reason, which may not be made clear yet.
So either way, actually, it's still way better for us to embrace differences and listen to each other for a richer working environment and output. Diversity is only a barrier when you choose to look at it that way.
