♪ Ohhhhhh the Orthodox hate the Catholics ♪ and everybody hates the Jews! ♪ And the Muslims hate the Orthodox
Orthodoxy doesn't hate people, as the Bible even says to love enemies.
The clearest example that Orthodox don't hate Catholics is that they do not have to get re-baptized when they become Orthodox. Also, Patriarch Bartholemew said that when there is no church of one's denomination within a commutable distance, they (Orthodox or Catholics) can commune in the other's church, as I understand it.
As I understand it, the least-liked religious group in America is actually the atheists.
Finally, I highly doubt that Muslims hate Orthodox as a blanket rule. In fact, there is an amount of respect for them as People of the Book, and despite wars and even harsh discrimination, they generally teach that Orthodox are allowed to keep and practice their religion, which is not what they teach regarding pagan religions.
Nonetheless, why do we have to accept whatever a government, society, or religious community does, without criticism? In fact, shouldn't one oppose their abuses?
