While your second post may have helped clarify your posistion, your first post made it sound like you came off as the jack ***. If I ever encountered somebody on public land telling me I couldn't hunt in an area I would be offended. It isn't your area / road even if you are there first. Yes, I probably wouldn't have even hunted the same area if others were already there, but you don't know what he really had planned. He may have been continuing on to another clearcut, etc.
Many years ago, I arrived at a trailhead in MT and started a long 5 mile hike into my prescouted area 2 hours before light. There was a horse trail going most of the way, and I began plodding down the trail. About a half mile from the truck I encountered three hunters who stopped us, told us there were elk ahead, and we had to wait until daylight with them before proceeding. We indicated we still had 4+ miles to go, and would try not to spook the elk, but we were continuing on. We wouldn't be anywhere near them come first light. They were extremely unhappy, abusive, and claimed we were ruining there hunt and they were there first. Not a pleasant situation, but it is public land. I usually hunt so far in to avoid these confrontations, and in my expereince when meeting other hunters they rarely hunt where they say they are going.
Seek more secluded areas, and move on to somehwere else when the blow hards arrive.
