I think it is important to ensure that Pride events are not just supported by self-identified LGBT people. One of the reasons for Prides is to let people know that they don't have to be ashamed of their sexuality. Being heterosexual, being bisexual, being homosexual...it shouldn't matter.

I did wonder if I would get hassle for wandering around holding Oilrig's hand at Derby Goes Pink but in the end decided that it didn't matter.

Sorry to hear you got hassle. :( Glad you did a good job. You'd have been complained about more if someone had been injured. :-/
