Surely the essence of democracy is that minorities can become majorities by persuasion, by urging the merits of their case. A prime example is the eventual abolition of capital punishment in the UK.
Minorities do not usually help their cause by abusing majorities and also not engaging in civilised debate. Majorities have a duty to respect minorities and listen and, if possible, react to their concerns.
As an example [above] of how not to persuade people, try: a perfect combination of self incriminating hypocrisy.
