Except where they're not.
1) Is pretty much true and you'd experience this if you ever tried to hike a busy MTB trail like Pontiac Lake or Island Lake. There's a lot of oblivious MTBers that don't think twice of not announcing themselves and rudely blasting by you, missing you by inches as if you're merely an annoyance in the pursuit of their Personal Record Time. I sometimes experience pretty much the same thing with an added exhaust bouquet while riding in the snow, as snowmobiles blast by me when I'm on a bike.
2) Is pretty much well documented to be bunk. Horse riders do the most damage by far, hikers are second worst. Bikers can and do cover more ground than hikers but most (far from all) know not to skid or ride in mud causing erosion. Some are just way too busy being manly and rad to be responsible though.
3) Is certainly somewhat true. Most of us have been hurt or know someone who has been hurt riding MTBs. It's a fact of life given the higher speeds involved and all the trees, sticks and rocks present when you fall.
I guess that won't satisfy you much though if you're a fundamentalist anti-Vandeman party liner but it's really OK to admit that we as MTBers are not perfect angels and that we can indeed tell the truth.
The mountain bikers won’t tell you the truth:
1. The presence of large, fast-moving pieces of machinery (bicycles) on trails drives away all other trail users — a net harm.
2. Mountain bikers travel several times as far and as fast as other trail users, thereby causing several times as much damage to trails, wildlife, and wildlife habitat.
3. Contrary to their claims about the healthfulness of mountain biking, it is actually an extremely dangerous sport. Serious injuries and even deaths are common. Recently a 12-year-old girl DIED during her very first mountain biking lesson!

By all means, please protect our scanty remaining wilderness, but as official Wilderness — the highest protection available, and the only one that does the wildlife justice.
Thank you,
