(Just by the by, there's a short story by Alexei Sayle, "Who Died and Left You in Charge?' which touches on the issue.
If memory serves one character is a timid cyclist with a child on board who has rational reasons but a guilty conscience about taking a short one way stretch the wrong way to avoid a longer, more dangerous route. Another is a transvestite stepping out as a woman from Transformations near Euston, frothing and wishing death to rule-breaking cyclists. I've found an online quote from the story:
[size="-1"]"That really does make me mad," he says, clearly riled. "Careening through pedestrian crossings, going the wrong way up one-way streets, yet so smug and happily anti-social. And I can only say that being a cyclist myself.)
Anyway, for the OP's survey of opinion and speaking as a cyclist who never jumps a red light intentionally I confess there is a short one way stretch I regularly take the wrong way. I'm not proud of it but I'm not ashamed either and my admittedly self-serving thinking is possibly based on what deptfordmarmoset wrote.[/size]
