My pagan idols were already victors long before Christ's alleged lifetime.
Their legacy idolised by Christian's themselves up until this day. Calling Alexander or Octavian Christians or losers is a laughably bad take.
Christianity is rapidly declining all thought the west and being supplanted by atheism, paganism, East Asian religions and Islam.
Your argument that Christianity won and is superior is based on false historical revisionism. Christianity took hold in Rome by Emperor Constantine royal decree and pagans were oppressed by the might of the roman state, not because christianity is a better religion.
Christianity has spread throughout the world by missionaries and colonisers who destroy native peoples and cultures in order to spread. The inquisition, the Salem witch trials, many more horrific forms if oppression and torture has been fished out in the name of Christianity.
