The belief that the other side is too extreme, so logic no longer applies.

means Holding ideas or pursuing methods so far outside the mainstream that most people consider them dangerous or unreasonable.

from Built from 'extreme,' from Latin 'extremus,' the superlative of 'exter' ('outer') — literally 'outermost.' The '-ism' was bolted on in the 19th century to name it as an ideology rather than just a position, turning 'being at the far edge' into 'a creed about staying there.'
