Three syllables good, four syllables hard

With the presenter of The Religion Report and a Christian guest having a discussion in which they both use the adjective 'evangelical' where 'evangelistic' is meant, and where 'evangelical' Christians are patronised by both parties, it makes for a spellbinding program on inter-faith dialogue. I could fairly hear, rising across the land, the hackles of veritable hosts of evangelical and evangelistic Christians. Thank God, I am neither.
