Much ado about nothing

Sometimes I worry about speaking out with my opinions. I find myself irritated (occasionally) when other people seem to have an opinion about everything, and they will tell you what is what in no uncertain terms. And heaven help the person that disagrees with them! I don't want to be a hypocrite, so I try to only speak out judiciously, when it is important or when some side of the issue is not being seen.

I also think some people have a tendency to make mountains out of molehills so to speak. They rant and rave about their opinion (whatever it may be) in any forum that they can find. It seems that relevancy and couth are non existent while they are proclaiming their opinion to the world.

So while I sometimes think I should have a little more courage and state my opinion instead of being scared, I don't want to become someone who yells just because they can.

What do you think? Am I over analyzing?
