Absolutely, otherwise you should just resort to perfect conformity and become exactly what everyone else wants you to be.

Its like a question in an exam where your the only 1 who got it right.

I think Socrates would argue that you should give your life for the truth. What is objectively right is always something worth fighting for, even if it is a losing battle.

As Sam Gamgee from Lord of the Rings tells us, "there's good in the world, and it's worth fighting for."

Informed, educated, good people have the duty of fighting for what's right.

If right and wrong do exist then it's trivially true that you should do what's right. If there's no right and wrong there's no stopping you.

Most assuredly. It is important to do what is right for you.

I honestly think it is better to fight for what is right, than to allow others to dictate your actions and standards for you. The phrase "be the change you want to see in the world" strongly resonates with me, if you wish to live in a society that holds the standards that are important to you, you have to lead by example.

Who really wants a value consensus? We need this disagreement and self believe to form new ideas and development. No matter how out numbered you are always fight for what you feel. Debating is important, to understand all reasons for all ideas, this may lead to you changing your idea and internalizing. However, don't just cave in, they might turn to your side and you might change the world.. even just a little bit.

Yes. I always believe that it is not what others think; it is what YOU think.
