Good thread and I agree with Ramble~On. I think most of us have both experienced and harbored prejudice of some type through our up-bringing, social environment, and interaction with others. Once stereotypes of any kind are established within us they're extremely difficult to overcome. I believe no one escapes this fundamental truth as we are all less than perfect. Admittedly, I continue to work on this as I've realized it's hard enough to keep track of my own business, let alone that of anyone else. I do believe the key is to assume the personal responsibility to accept others openly without hatred, fear, and prejudice if we are to find true contentment within. It is also our responsibility to be mindful of others and to not be “in your face” while expressing our views to provide a reason for them to disrespect us, as we generally get what we give. In the bigger picture it's not what others do or who they are, but more importantly, it's how we react and interact personally. Hiking the trail is an activity that should be rewarded with contentment and it would be a shame to ruin the experience with negativity of any kind. In my experience most people on the trail see others as hikers and nothing else with a common respect for all. As long as we respect others it will generally be returned. I'd say tell them to hike giving others the same respect they seek and all will be fine. Hope they enjoy the hike!
