My example of a sick wife was not meant to combat the morality of the policy. It was intended to combat your idea that you can fundamentally decide the morality of a return from your desk chair.
I hardly decided you were a judgmental curmudgeon. Perhaps it's useless to explain, since as you said, you're refusing to change, but perhaps I can enlighten you to a different perspective;
Don't worry about it. Why are you worried about it? Ask yourself what it does for you, or anyone else, to declare it wrong in a forum and publicly condemn a few hundred strangers to your blacklist.
Taking a stand and saying something is all well and good when there's real harm. However, REI and Backcountry and L.L. Bean are making money, expanding, producing jobs, and opening more stores- all while their return policies remain somewhat the same. So, there's really no "cause" to fight for at all.
When you spend time judging people you don't know, you waste time. "We all form opinions" is mostly true. I'm guilty of it myself. But clinging to those opinions like the lever on a guillotine is terrible karma. You're better off investing your time in yourself, or in your positive interactions. I try to shake the habit whenever I can. I don't know you, so I'll give you the benefit of the doubt in any question of your platitude, and ultimately, I will feel better and be more inclined to treat you with respect. Not jsut you; anyone I encounter.
Judgement, for some people, is something that ends up ruling them. If you spin wildly trying to figure out who's wronged your sense of good, you'll forget to foster change by being a positive example with positive things to say.
