苟同 is a formal verb meaning 'to agree unthinkingly' or 'to readily concur without careful thought'. It is almost always used in the negative — 不敢苟同 ('cannot agree', a polite way to disagree) or 不能苟同 ('cannot share that view'). You'll encounter it in written arguments, formal speeches, or literary contexts; it carries a tone of mild criticism of others' agreement.
