I think that one individual can make all the difference. After all, the greatest movements of change in history, whether positive or negative, came about because of one individual - like Gandhi, Mother Teresa, Nelson Mandela, Martin Luther King, Abraham Lincoln, Hitler, Mao Tze Tung etc. Of course it is not easy to go against the crowd but it is possible. It just depends on your tenacity and perseverance. Even in Dorje Shugden lineage, look at the DS lamas - they have basically been on their own - look at Geshe Kelsang Gyatso and how the New Kadampa Tradition has grown despite being ostracised in the Tibetan Buddhist world. How did that happen? Through faith in Dorje Shugden and never giving up. So yes, i do believe that we can make a difference if we stand firm and do our bit.
