Ick factor aside, that sounds like a “No True Scotsman” argument to me.

Be aware that if I, as a lapsed neopagan, am asked to judge which Christians are acting in accordance with the deeds and words of an entity that I regard as fictional as my own pantheon, there might not be any “True Christians” left.

To focus on the point, how about a biblical example: Parable of the Sower, specifically that sown on the path and in the thorns.
