Read what Lucy Kellaway, "agony-aunt" of the Financial Times (London), answered:
You don't say why you object to this conformity, as if you expect the reason to be self-explanatory. I can see that being surrounded by posh, guffawing lads could be annoying if you aren't young, posh and guffawing yourself. But beyond that, you need to be more specific.

I can think of a large number of organisations that were founded on hiring spectacularly undiverse workforces: the army, the City of London, P&G, McKinsey, Microsoft, all of French industry, even the Financial Times was a few decades ago overweight in just the sort of person you mention.
