expression-requestsidiom-requests

Is there any idiom, expression or saying that would imply "this is a rational idea and there is no room to dispute, so one has no choice but to accept it" (i.e. "It is hard to argue against such rationale")?

I have found "if the cap/ shoe fitsŲŒ wear it", but it seems that it can be used in situations when that discussing (rational) idea is an acceptable criticism, so I don't know if I can use it also for all other rationally acceptable ideas or not.

I want to use it in:

James and Alex were arguing over a hot political issue, but after 50 minutes of continous discussion, James told Alex something which seemd so rational that Alex had no choice but to accept it, so Alex ended their discussion/ argument by saying:

"Okay, you're totally right, ___(= I can't argue with that, because it is rational and makes sense to me).

Best Answer

All of these answers accurately describe how one would claim that their own argument has no room for dispute, but your question specifically mentions the speaker admitting the other side has a point. Therefore, I would suggest the following:

  • "I can't argue with that!"

  • "You got me there."

  • "That's a good point."

  • "I'll give you that."

Inflection is important with all of these, and it might help to add "Well," or "I guess" to the start of each of them.
