I'm sure what Lolita meant that, however horrible Nazis are, at least as co-members of the audience in a concert their behavior would be less annoying, as they'd probably just stand there with their arms crossed, while HIM fans are, as Lolita says, usually 13-18 yr old girls who have a crush on the singer and think shouting and crying of excitement is the way to prove how much they like the band.
I feel your pain, Lolita, the same thing happened to me in Spinefeast when To Die For played- I couldn't hear the band over the awful shrieks of the girls standing next to me. not that I was missing much anyway.
