Nork's post is balanced and sensible, and I agree.

And I'd like to add that I've chosen my language carefully and nowhere have blamed all cyclists. I have noticed an increasing problem which is why I commented in the first place.

If something is getting worse and causing danger, it is worthy of discussion - even if only to compare perspectives with other road users.
I think it's a shame that the thread originally highlighted a worrying trend and it's got sidelined into blame and counter blame. All responsible cyclists should be equally concerned about the way a growing number of people are behaving. It does no one any favours to use attack as the best form of defence.

No doubt there are dopey pedestrians but I'm sure they don't go out of their way to put themselves in danger. I think cycling on the pavement and often being aggressive to pedestrians is a very deliberate act which is what prompted some of the contributions in the first place. No point in attacking those who are raising these concerns.
