Is the topic of discussion i) cyclists stopping at stop signs, or ii) the behavior of cyclists when riding with one or more other cyclists?
Re i) I wouldn't argue with any of the reasons or discussion above, for or against. I think the interaction of cyclists with motorists is a complex subject, worthy of both principled and situational decision making.
Re ii) Riding with other cyclists particularly if you don't know them or their riding style, can be more dangerous than not stopping at stop signs. In these situations my cycling behavior will change. If the other cyclist stops, I stop. If the other cyclist rides thru, I'll ride thru (cautiously) and then decide whether to carry on riding with this person or not.
