Like saying you won't purchase a particular type of soft drink because it
gives you gas and you are uncomfortable as a result. Of course, Neither
Pepsi not Coke will sell you a complete listing of their ingredients?


Hardly.
If my car goes wrong I expect to be able to fix it.
If my stereo (assuming it isn't a really cheap one) goes wrong I
wouldn't expect to fix it.

How would you propose fixing a soft drink ??????????
