The word "antidisestablishmentarian" may seem intimidating, but there are several synonyms that convey the same meaning. Some alternatives include "opposer of disestablishment," "anti-establishment," and "anti-state church." Other options include "anti-clerical," "nonconformist," and "dissident." These terms all refer to someone who is against the idea of dismantling an established church or religious system. While the word "antidisestablishmentarian" may be a mouthful, it is useful for those who need to convey a specific stance on the separation of church and state, and its synonyms provide a more accessible way to do so.
