Personally, I think both ends of these conversations could see improvement. A lot of people on here are rich and well-to-do so if you tell them the thing they bought for $45-$90k is more of a luxury than an environmental benefit or investment they'll get upset. Likewise, when rich people tell everyone their flatulents don't stink but others do, it'll make people upset, especially if the price tag to non-stinking-flatulents is high.

Civility and mutual respect tend to go a lot farther than "just facts".
