Why not take that road?
Perhaps because what someone (who has a clear agenda) chooses to display on a website in highly manipulative and imbalanced way isn't even a blip on their radar screen. Or perhaps if they did protest, they be met with the rejoinder of "If there is nothing wrong with this, what is your problem us displaying it?" which we hear frequently. Or perhaps the riders who use this technique successfully are busy riding. Is there an upside in responding for them? I don't see it.
If the intent of this and many other websites is to inform, the subject would be presented is a straightforward and balanced manner. But the intent isn't to inform. It is to inflame. I have a hard time responding seriously to that.
If you like to have your opinions spoon fed to you, carry on.
