I don't know how you meant that, but it reads very much like STFU or GTFO to me.
> The reason there's so much alcohol is because it acts as a social lubricant.
Except that alcohol is more than just a social lubricant; it's a disinhibitor.
That in and of itself creates an exclusionary environment for many women, because they can't rely on physical dominance to counteract the dangers that come with a large group of uninhibited men.
Apart from that; the simple fact that it might not be appealing to a large group of people you wish to involve in your community should be reason enough in- and of itself, much like how insisting on things like dirt-bike racing for team activities might be considered exclusionary for certain groups whom this would appeal less to.
