The question is not what can this person spend his money on, but is it an intelligent decision. You are well within your rights to cut off all your fingers if you so desire, but does that make it a smart choice? I wouldn't be so quick to jump on someone's right to voice an opinion in a public forum like this. It's a chat board about the hobby. This is a hobby related issue and all comers should be allowed to state their opinions as long as they are not vulgar or violent.
