Just so my posting "old idols" is not completely misunderstood...
Idolatry, one might say, is not a property of a deity. Even real, true, and authentic gods can be turned into a false god. Even professing Christians can turn their one true God into something else.
True gods are ones that are loved, which usually doesn't mean hugs and puppies. One invests the deity with personality. One has a relationship with the deity. The deity in some way in some sense is an aid and even stimulus to empowerment, self-awareness, and to becoming more than what one already is.
There are deities that are sources of fear, self-diminishment, and hatred above all else, because the deity is all too easily provoked to grotesque punishments. Such deities are better called demons and devils.
Christians who make their God into a source of fear and punishments run afoul of their own book:
Mark 3:29: But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation.
The glory of a deity is reflected by its followers. Consequently, the homophobic obsession of many Evangelicals means that they are blasphemers for Christ.
Or less controversially phrased: Christians are Christianity's best refutation.
