Lol, David, I too struggle and it is onerous indeed, but I still do my best to bring it to a positive ending. You can't with everyone, but those folks you know are so out of wack with logic that you can't, are better left to themselves.
One of the best parts of being non govt. these days is that I can and do choose my clients. You want me to do something I don't agree with and won't listen to reason, call the next guy and see if he is more open to your perspective, I'll pass.

A professor at Utah State in the Rangeland Resources Dept. had a great saying.
"If you are breathing, something else is taking a hit."
One of the simplest yet most profound statements and I've used it often in life since then.
Similar to the one mentioned at WCT a few years back.
"How would you like animals to die?"
Most people scratch their heads at these statements or respond, "I don't want them to die" but in reality
we and they are all dying, it is only a question of how and when.

Getting way off topic from Mike's thread not that it isn't the S.O.P. lol, but I honestly do enjoy debating folks
in a calm manner about how even growing veggies costs wildlife in terms of death and habitat while it benefits
others. The folks on the extreme end believing they don't kill anything or harm anything are not thinking even
on the most basic level about food and clothing and shelter and how these things are transported, created and
so forth.
Maybe I just like the challenge! I'd say it keeps me young, but the gray hairs starting to appear in my beard would
argue that point!
