The moderators of this forum have unfairly cut my posts from the Magicshine thread here, describing technical flaws in other headlight comparisons and argueing against strobe headlight use at nighttime. All because ONE ignorant member can't handle it. THAT's how the bicycling community reacts to criticism. THAT's typical of bike club members and ANY criticism toward them and their precious helmets, precious helmet mounted lights shining into peoples' faces, and paranoid belief in overlighting to satisfy their personal belief that "more light equals more safety".
So how can there be any real rational discussion of "etiquette" when the PC police here are biased against real alternative perspectives? There can't. Everyone's free to agree. Everything must be happy, happy, joy, joy. Incorrect and misleading information about how bright lights are is promoted because it's done in agreement with the beliefs of those people.
