I know this feels rather novel and even strange in the Canadian context, but other postal systems around the world have integrated shops/markets/other services for years.

You're just telling on yourself that you just don't care where your money goes. And, you know what, that's your call to make. But what I don't understand is why bother attacking people who choose differently than you? Why do you care what random internet people you don't even know think of you? Who would even know how you choose to spend your dollars if you didn't say anything?
If you don't care where your dollars go, just own it. "I've got too many other more immediate things in my life to worry about." Okay, then. Fine. Just own it, and stop being so insecure about it. If you're right, then you're right.
"You're not perfect, so don't even try" is an incredibly childish and immature stance to take. That's like saying no one should ever try or learn anything new because they're not masters of it immediately. I mean, if that's the attitude you have, why should you even bother anything ever? What is the point of your life if you're not the best or perfect at everything? You may as well just go and die already.
