I think perhaps if the venue has had problems with guys date raping girls - Its not massively an inconvenience for me to undergo a little search on entry. Happy to do so if its in the name of making gigs safer. Id rather be searched for no reason than them not search a potential rapist for the reasons of upsetting people who did not need to be searched.
However Its a bit weird getting questioned about knowledge of the band and thats a bit silly. I mean would security know if i offered up a load of made up song titles. Is. knowlege of the band a pre-requisite to seeing them - im not sure it is.
Actually, I think I'd argue that both young and old people are far too obsessed with watching aging bands. But that's a totally different situation.
I think men need to understand how their presence can make women feel uncomfortable at gigs, and understand that being asked a couple of questions as you enter a gig is a small price to pay for women feeling safer attending events on their own.
