Fair game? What say you, should fair rules be observed when going after fair game?
For example, both Testament of the Bible have accounts of sackcloth and ashes being used as symbols of grief and lowliness--and also of penance. Jesus commented that had his miracles been performed in Tyre and Sidon, they would have repented, sitting in sackcloth and ashes. In the Old Testament the practice is noted in the Books of Job, Esther, Jonah, Jeremiah, and Daniel. As early as the second century, there is a record of some Christians swearing they could repent without demeaning themselves by the use of sackcloth and ashes.
Yet some here--quite familiar with Jewish roots of repentance and grief using sackcloth and ashes--look up non-Jewish roots of pagan religions also using ashes and testify that Christians follow the pagan roots, not their Jewish ones. Yet, they cannot even get their stories straight about which pagan roots can be traced to Christianity.
In the late 1800s, some atheists tried to trace Christ's death and resurrection back to Greek and Roman mythology. When I came across this as a teenager--being a huge fan of Greek and Roman mythology--I decided these people had been idiots--or to be kind--simply ignorant of Greek and Roman mythology. Later I was happy to see the late 1800s work had been debunked in the early 1900s.
The problem with nearly everyone of no faith or of a different faith is that they want to tell the world what others "really" believe--and/or their "real" history. They also want to tell the world why believers believe--the most popular nonsensical "reason" being because believers obviously fear death.
The true answer is much more simple. We have met (or noted) God in our midst. Non-believers, for whatever reason(s), lack this perception.
If faith, religion, Church, Temple, Synagogue, are fair game, then let the rules for criticism, attack, be fair.
