iconoclastic

Synonym discussion
Sense: adjective/1
All four words describe a departure from the norm, but iconoclastic is uniquely concerned with attacking established beliefs. 'Radical' is the broadest — it can describe extreme political, social, or economic positions without necessarily implying an attack on tradition. 'Revolutionary' focuses on bringing about a completely new system or method; it is more constructive whereas iconoclastic is more critical. 'Unorthodox' is the mildest of the group — it simply means going against the usual way of doing things, without the aggressive, attacking tone of iconoclastic. 'Dissenting' refers specifically to expressing disagreement with a particular view, policy, or authority, rather than targeting tradition as a whole. For example: a painter's iconoclastic style deliberately rejects artistic conventions, while the same painter's unorthodox choice of materials is merely unusual, not confrontational.

Etymology
The word comes from 'iconoclast', which was formed in the 16th century from Greek 'eikōn' (image) and '-klastēs' (breaker). It originally referred to someone in the 8th–9th century Byzantine church who opposed the use of religious images. Over time the meaning shifted from the literal breaking of images to the figurative attacking of established beliefs and institutions.
