By your logic, any purchase is ignorant. According to what you're saying, it would make me ignorant to; -Buy food at a restaurant. I have no clue if my food is going to look just like the picture on the menu. -Buy a movie that I haven't seen before. -Buy literally ANY video game without playing a demo or participating in an Alpha/Beta. -Buy an album containing songs I've never heard before. -Buy a candy bar that I've never tried before. -Buy a drink that I've never tasted before. -Buy a new Alternator/Timing Belt/etc. for my car. (Not everyone knows what they do). -Buy a new cellphone (Who's to say I know everything about the model of phone I'm buying). -Buy a new gaming Headset/Headphones (Who's to say I know if the quality is going to good or not). And many, many more. So, by your logic, literally every person who has ever purchased anything new is ignorant.

Pretty much. Each and every one of the items you listed will have reviews available. I suggest looking at them before a purchase. My question to you is. If you bought a candybar you had never tried. Would you go to forum and bash it if you didnt like it?

Stupidity on your level can't be argued with.
