Getting an opinion in order to guide yours is one thing, relying on it to make your judgements for you is QUITE another. I've seen more of the latter in relationships. People distrust their instincts and personal preferences just to go along with the popular consensus.
I don't see what is so non-controversial about people who form their opinions solely based on others approval? If we, as individuals, are basing our judgments on social consensus instead of our own judgment, then we are in a LOT of trouble. Just to give a macro example, it wasn't too long ago bigotry against homosexuals was a opinion people fed into each other. They'd say "this persons is gay, don't hang out with them". If we would have used this social logic, we would still be a country of homophobic bigots.
GEORGE BUSH was a popular President everyone and their mom would have approved of in 2001... need I say more about basing your personal judgment on your social circles opinion?
You're friends do not know what you personally want. If I would have listened to my friends, I would not have even admitted I liked tickling.
