I think the creator of that thread had the best intentions. But was, like most of us, not able to take the necessary distance from the topic. Speaking for myself, flashaholics are mainly solution oriented. So it boils pretty quick down to the question: what rechargeable Li-ion light can you advise to a homeless person.
The question should have been more something like: if a homeless person is in need of a personal light, what kind of light would you advise him/her. Starting from matches to a thunderbolt, with everything in between, and narrowing it down later.
The number of officials from the other forum that were involved in this short thread (before is was closed) makes it clear to me that the bearers of those lights do not belong to the target audience of said forum.
