Yes, I see that you are making the distinction. I'm saying that most don't. When "off-road educated" people say it's ok to toss biodegradable trash, some people won't make the distinction. Not necessarily here on RME, but out in the field, etc.
It's a mix. Some FS Rangers I know will write tickets for tossing orange peels. Others I know will toss orange peels themselves.
I personally do not toss any trash biodegradable or otherwise, and all I can do is encourage others to follow the same policy. I don't like to pull up on a nice picnic spot on the trail, and be greeted by peels or any other biodegradable waste. I've been out on extended trips where I felt like I could have been the first person travelling there in years. Then I see the trash, and the illusion is broken. Just my way of looking at it.
