Your lack of desire to take seriously your responsibilities to those you share the sidewalk with is a problem for me. You want to be on the sidewalk so you'll be safe, while at the same time, refusing to acknowledge any risk you're imposing on others. That doesn't fly with me. Slow it down, sporty.

Clearly this is an issue of religion. If so, then just declare your side, sharpen your pitchfork and be done with it. But arguing as this thread does, that riding on the sidewalk for safety is "equally unsafe" needs to be done with evidence. It's certainly not true that the collisions are independently more dangerous. Maybe you could argue that there would be more of them or something.
