I went as a viewer, yet didn’t want to be mistaken for an indifferent accidental viewer. The rainbow itself felt like a symbol that focuses on sexuality, including kissing (!?). On the other hand, the black-grey-white-purple asexual flag is a bit boring (and not so right as well, I do like some characters, even the real persons in a somewhat sexual way). So I’ve just printed out the Windows Colour Picker, where everyone can choose their shade of grey-and-colour, and feel truly included. (I hope a hint of irony isn’t too hard to spot, as well).
And as all other marches, this one starts at my doorstep and ends here, displaying all the propaganda all the way to the centre and back, while going on foot.
