Opinion: an essay with an opinion

My opinion about having opinions is that, you can express them and still get the same sad opinions in return or the complete opposite in which you will have to fight people to keep those opinions.
    I have often thought having opinions means you have a mind and having a mind means you can think for yourself but that's not entirely true. Sometimes we follow other people's opinion because we are docile in that human way where we try to conform for fear of ostracization, fear of being different, etc.
    Everyone have opinions and we must respect that even if they might have opinions that are best kept locked up. But once something is said, it cannot be unsaid because someone will have already make a big deal out of it and maybe a mob of people will try to wrestle the originator to change their minds.
    I think we must say what we want without trying to please others. We shouldn't indulge people who sob every time they hear something they don't like. But one must know when to shut up and when to speak, right?
    This rambling is brought to you by the food/alcohol we will consume when our opinions get ignored or demeaned.

What's your opinion about opinions? Should you share them or keep them to yourself?
