You know, I can sell you a hand gun. You can decide to use it as a device of protection or you can use it to hold up a convenience store. That is your moral choice.
You’re ignoring the fact that China has an evil government that is doing incredible harm all over the world with the money it gets from the US in the form of crap goods that we have no choice but to buy, since globalist companies have moved their manufacturing to China to take advantage of cheap labor and no envirnomental laws.
Now the US has lost its manufacturing base, jobs are hemmhoraging, and all we can buy in stores is crap from China. Toxic, ill made crap.
To make your analogy more accurate, the gun dealer is also a pimp, a member of a drug cartel, and the guns he sells are cheapy crap ones that explode in your hand or misfire. And there is no other gun dealer because he undersold all the others or threatened them to shut down.
