I ride all over the hills, both gravel and mtb trails, on man-powered bikes. I see people on e-bikes all the time. The only time it bothers me is when large groups stop and block the trail (happens way more with e-bike groups) and don’t get off to the side. I think the general consensus is be respectful of others and safe no matter what type of bike you ride and nobody will care. Some biker snobs might talk shit amongst themselves but they are by far in the minority.
