Satanists host public event at Civic Center as Christian groups pray outside

[Shooter]

If Satanists or Atheists did this for a Christian rally at the same civic center, then this would be a national headline with outrage galore.

You are probably right, but not for the reason you are thinking. If it had made news, it would be because atheist groups were complaining about a Christian group using a civic center owned by city government, for prayer.
