My first point was that this isn't gender specific. My example was - I don't touch alcohol, I don't like ping pong, or consoles, or any of the things that people hold up as "bro" culture. But nor am I going to hold it against a workplace if they want to offer those things.
It's not a negative - it's just a thing.
For example - nursing rooms for mothers, or Muslim prayer rooms. I may not use them personally, but I don't see why it's a negative if they're there.
My second point - I have worked in a whole range of companies, from formal to very casual - and for me this is much of a muchness.
To your points.
You claim that we should be suspicious of companies that push "we're so fun". I don't see why it's a warning sign, any more than a workplace that pushes the "we're so formal" is a warning sign. You need to make your own judgement, based on actually interviewing there and interacting with people - and more importantly, one that fits your own ethos and preference.
Some people like formal cultures, some people like more jovial cultures - we shouldn't box them as gender specific, but just something that is unique to each person.
Alcohol likewise - that seems a personal issue, as opposed to something gender specific, or a company directive.
Like I said - I've worked in banking, and trust me, there's a drinking culture (among other vices...). But really, it's a matter of self-control. I never once felt forced to engage in that behaviour if I didn't want to. Perhaps I picked a good firm, or just had good mates.
My point is - whether there's alcohol available or not is a red herring.
And I don't think alcohol is somehow specifically a male thing - once again, I believe it's a personal self-control thing.
I don't drink alcohol - but if somebody is drunk, whether they're a guy or a girl - or whether the gender ratio at my workplace is 60:40 or 80:20 is irrelevant. They are drunk. I'm certainly not going to say - "Oh you're a women but you're drunk...well, that's OK then". Although to be honest, if you're drunk and not causing me any harm, meh.
Gender or alcohol isn't a shield to cover your behaviour - and that flows both ways.
