That's exactly the attitude I am referring to, but lots of contributors to this thread have understood that the Belles are peed off because some male offered to help with a mechanical.
This was not the point of the op!
He asked very politely

He's not just "some bloke"
Why? This is a cycling issue for sure, don't you think?
Exactly.
I have learned much from other women cyclists (from
@Telemark and
@flyingfifi for example) but, for a start we knew each other, for a second the learning resulted by me asking, by observing, by them suggesting, not by imposing.
Well, it used to happen to me cycling solo maybe once a year, if that.
That was when I hardly saw any cyclists around, up until maybe 2 years ago. The increase of unsolicited male patronizing comments coincided with the increase of cyclists in the area.
Never used to happen on a Belles ride.
Now it seems to happen almost every time we are on a fun ride, I think we give the impression of a motley of hapless women that need to be enlightened on how to ride ... in a man's way!
Tbh, I'm beginning to change my mind after reading all the answers on this thread.
Could it be that man gets it a lot from man too?
That would not change my stance though: I am not having it no more, next guy to do this to me is gonna be at the receiving end of a very sharp (verbal) lashing.
Adult cycling for commuting and for fun is a "new thing" here.
I am one of those started cycle commuting in my late 40's seeking an alternative to public transport and for a personal challenge too.
The fun part of cycling for me came a couple of years later, when I discovered the newly formed Belles and the CC Ecosse rides.
Previously I was looking at drenched cyclists, all helmets and hi-viz, without really registering, vaguely thinking "how/why do they do it.
Of course, the Sunday club racers were obvious to me, they did it for sport, I did not know one would do both types of cycling.
The ones I saw were invariably all males, apart from the girls in University land.
It did not occur to me, then, that I, an ordinary middle aged woman, could go wherever, whenever I want on a bike.
I knew I had much to learn when I started cycling, but as an older woman I did not think " this cycling is a thing that mostly men do, can I do it too? "
It was a thing that mostly nobody did here, so we started all equal!
I feel, though, that a younger woman, not so self confident, could be put off cycling if a series of such patronizing episodes were the norm.
