June-Bug and Perna,
You both pose very valid points; however, from slightly different angles. When the object/idea/belief is subjective in nature (everyone should go to college), it is absolutely okay to have your own view of things/the world, etc.
If the object/idea/belief is objective (the sun is yellow), I do think it warrants to investigate how the rest of the world sees these things. Obviously and without doubt, there is a continuum here with vast amounts of grey areas so this is the best I can do for now
