You're not wrong, but you're missing the point. Nothing was impeding this use of the trail. I was impeding his speed on the trail. It does absolutely matter that he was on an e-bike. Like I already said, my opinion, further solidified by many of the people here that are clearly e-bikers, is that if you're on an e-bike, you can sit up and slow down until you can pass at your leisure. Anyone on a normal bike, on a climb should not have to change their ride whatsoever because someone else is using assistance.
I saw where you posted a link to the trail. I watched a different video with a full run. It looks like a fun trail.
With all the cactus, rocks along the side of the trail, and cliff sides, it looks like that trail has a serious challenge for passing. There is very little opportunity for a brute-force overtake. Even for an e-bike.
Which makes it even more important on that specific trail for everyone to extend all possible courtesy to all other trail users. Otherwise it devolves into race-track mentality, where nobody gives the courtesy of announcing themselves for fear of being blocked. Where people make risky passes because they won't be allowed by. Elbow bumping becomes common because nobody is willing to let up to let others pass.
Such highly limited passing requires MORE "share the trail" good stewardship of shared trails, not less.
You came here and requested all of us tell you whether you were a jerk or not. So I'm going to tell you what you asked for, whether you like the answer or not.
"....
should not have to change their ride whatsoever because someone else..."
That's a jerk attitude. That's what earns you a "Yes" vote on being a jerk.
EVERYBODY must change their rides to accommodate other trail users. ESPECIALLY when trail conditions are more challenging. That is the whole point of the entire "Share the Trail" philosophy. Not just assert your full "rights" against other trail users just because you can. Find opporutities to change your ride in ways that promote sharing the trail.
That's true EVEN WHEN you personally dislike their mode of trail use.
Scratch that. That's true ESPECIALLY when you personally dislike their mode of trail use. You should have responded to him exactly the same as if he would have answered "I'm a meat-bag pro-rider".
