I did the York one a few years ago. It was a blast, only slightly marred by the presence of a handful of male participants whose only interest in the event was blatant perving of the female riders.
I would be interested in your definition of "perving" or "pervert" - the latter a very dodgy word in my opinion. Used to be chucked around a lot by 13 year old schoolboys. I remember them doing it as, er, a 13 year old schoolboy.
If folks appear naked in public I hardly think they can have rights on how folk look at them.
This might be as fearless eco warriors or with an interest in the naked flesh of their preferred gender - possibly both.
Anything approaching assault or interference is of course off.
Can't help but think a lot of this curious "look don't look" attitude is very dodgy and about control.
It is also just possible (for "nowt so queer as folk" to use that wonderful humane northern phrase) that some of the supposedly mainstream riders on the ride have less than great political credentials and actually get a kick out of exhibitionism. Which is not unknown in folk of whatever gender. I have also known a fair few political exbibitionists who didn't have to take their clothes off to pander to their (true) ego driven motives.
Would suggest if folk don't like the public looking at their naked body they don't take it out in public.
By the bye, in case folk are wondering, I came back to this thread which I had long forgotten about because someone liked one of my earlier posts and the forum software pinged me.
edit - no "perving" from females? or is that not a thing?
