As with politics we often must do with the best we can, all things considered. As an alternative to Amazon there is Walmart, often cheaper though with less variety, but who are just less liberal.
If you want to predicate your purchasing on political appropriateness, you'll have to move to the woods, build a cabin, and live completely on the land.
Agreed but it is very tough as the left coopts a lot of business these days. Unless one becomes a hermit and never buys anything it will be difficult to be pure. I avoid the most egregious companies if there is an alternative but if none I bite the bullet and get what one needs. Fortunately my needs are minimal.
