I find first person shooters offensive yet I do not hear calls for the promotion of such games not be allowed at a gamers' event. If the event is supposedly to "offend no-one" then in all likelihood you will find that there is no event. Yes, I do know people who declare they are offended by ALL computer games. My preference is for turn-based strategy, but I would never seek to impose my preference on anyone else.
There is no shortage of wimmins (sic) events of all sorts being held around the world. If you are so concerned you could conceivably organise a wimmins only event. No dancing girls. No nerdy young blokes allowed. Naturally the wimmin would object to you, a bloke, organising that event. All in the interests of equality and not giving offence of course ;-)
