opposing the democratic way

there are so many issues such as abortion, gays in army, what is socialism, on which groups and individuals differ. in democracy you are supposed to go along with majority opinion.

however some people seem to be doing too much drama (media loves it) and have destructive way of opposing , they collect masses sometimes (misguiding people) and shout, wave placards disrrupt speeches etc.it has really no purpose but a good media spot.
