There is an article on my local newspaper's website that talks about our small towns north and north-east of the Denver metro area planning for the expansion and connection of trail systems in our vicinity to form our part of the large Colorado Front Range Trail. The story provoked a single, anti-bike response on a website well-known for its negative, unintelligent criticisms and personal attacks. I was going to respond to this, and still might, but I thought I would use this example instead to improve my debating skills on this subject (and perhaps in general) by reading your hypothetical responses to this person's comment.
Now, of course, the first option is to do nothing/ignore the person altogether, especially considering the overall quality of the comments on this website and pointlessness of the resulting arguments, but I think that leaving these comments unchallenged, especially when it's as personally relevant and myopic as this one, imprints or reinforces those perceptions on the part of other readers of these comments.
So, I ask for your help: What would YOU say in response, not necessarily to change this person's mind, but to represent the other side with greater cogency for the wider, silent audience? (hardly a new concept, I'll admit)
