“Democracy for the cast majority of the people, and suppression by force, i. e., exclusion from democracy, of the exploiters and oppressors of the people - this is the change democracy undergoes during the transition from capitalism to Communism.”

Context: Democracy allows people to have different views, and democracy makes it also -- makes us also responsible for negotiating an answer for those views. [... ] So we would like to -- it’s not just a matter of debating the case in parliament and winning Brownie points or Boy Scout points, or whatever they’re called. But it’s just a case of standing up for what we think our country needs. And we would like to talk to those who disagree with us. That, again, is what democracy is about. You talk to those who disagree with you; you don’t beat them down. You exchange views. And you come to a compromise, a settlement that would be best for the country. I’ve always said that dialogues and debates are not aimed at achieving victory for one particular party or the other, but victory for our people as a whole. [... ] We want to build up a strong foundation for national reconciliation, which means reconciliation not just between the different ethnic groups and between different religious groups, but between different ideas -- for example, between the idea of military supremacy and the idea of civilian authority over the military, which is the foundation of democracy.
