This issue involves democratic decision-making and the value of minority opinions. Numerically speaking, 80% support does constitute a majority decision. But this does not automatically mean that the opinions of the two opponents are "unimportant." In different situations, the importance of minority opinions will vary： 1. In the simple majority decision-making mechanism, the majority opinion will become the final decision, but this does not mean that the minority opinion is worthless. 2. On issues involving basic rights, even the rights of minorities should be protected 3. Minority opinions may contain important insights or point out risks that the majority ignores 4. A healthy decision-making process should listen, respect, and seriously consider minority opinions, even if the final decision may not be adopted The ideal decision-making process should balance efficiency and inclusiveness, so that decisions can be made while respecting and absorbing different perspectives. In many cases, seeking a broader consensus is more valuable than simply relying on a majority vote.
