difficult to do; is unreasonable
Expresses that something is unreasonable, forced, or difficult to justify.
This pattern is used to say that an argument, explanation, or claim is unreasonable, has holes in it, or is a stretch. It implies that the logic doesn't quite hold up or that the claim is too far-fetched to be accepted. The subject is often a statement or theory, not a person.
It carries a critical tone, so it's often used when pointing out flaws in someone's reasoning. It can also be used about a plan or action that is unrealistic. In speech, it tends to appear in more formal or intellectual contexts, like discussions or essays.
