As a President of a country, especially if he is a so called Buddhist, he should welcome and promote religious freedom because it will create harmony in his country. People accepting each other faiths and believes have far reaching effects of peace loving and harmony society. One who bans, and forbid other religious rituals to be held, are more of a selfish act which can lead further inter faith conflicts.
He as a President, to promote no killing of animals, he should educate his citizens as a whole not just targeting the Hindus to have better way or find an alternative instead of sacrificing animals.
If this goes on like what Ensapa have listed, The country will have conflicts for a very long time to come.
