A person who opposes or rejects Romantic ideals, philosophy, or artistic movements.
From anti- (against) + romanticist (an adherent of Romanticism). The suffix -ist denotes a person who practices or believes in something.
An antiromanticist would be the person rolling their eyes at sunset poetry readings—they existed in the 1800s as serious philosophers, but today they'd probably just be called 'realistic' or 'practical.'
