I do recommend paying down credit card debt, unless there is absolutely no way you can do so (which is more common these days). And limiting use of credit card to situations where it is absolutely necessary or the benefits exceed the cost of the debt. Even when investing in silver, I recommend extreme caution when using credit cards because you don't know when the market will go way up--or when they are going to play a game and drop the price of silver, then force you to sell it to pay down the debt.
But, donating to the Worldwide Pedophile Defense Fund is NEVER a worthwhile use of credit. Get the damn card paid off if at all possible, and keep it that way until you run into a real emergency situation or something that will give you more benefit than the debt will cost. Perhaps to invest in a new business (in some countries--it seems that certain countries are doing all they can to make these ventures illegal). Perhaps to move to somewhere you are more comfortable living--which you cannot do if you max out your cards for the Worldwide Pedophile Defense Fund. In fact, even if I had plenty of cash on hand, I wouldn't donate even one toilet paper to them--at today's prices, if you have an extra 3 toilet papers to donate, you are better off using them to buy a silver dime.
