text: The finial reason is that sometimes people need advice from people that share there believes. One example is if a Republican asks a Democratic for advice. Or if someone has a different religion than you and you still ask them for advice. You probably will get some advice that works, but depending on if your topic is more controversial on what you need advice about you can get advice that isn't right for you. So generally you should ask someone who you share believes with. If you just let the person give you advice and you follow that advice you got people might suspect something since it might not be the way you usually act.
