Sometimes we all come across people that just dismiss our ideas or thoughts by saying “that’s nonsense”. So I was wondering what would be some good responses to that in general? Any ideas?
Good comebacks would also do but serious answers are also welcome. I mean I don’t always feel like explaining to them what I am saying is not nonsense because sometimes people just don’t want to listen and use this expression to simply end the conversation, which is a bit rude to be honest.
“There’s over 7 billion people on the plant. The vast majority of them will never be my friend. Thank you for saving us the time by self-identifying as to which side of the fence you’re on. Good day, sir.”
The best response is probably ‘why is that nonsense’ but that will lead to a discussion with a person who isn’t able to have a discussion, and is probably a waste of time.
If you really feel that the person has not given your ideas fair consideration, this is sometimes applicable:
“Your face is nonsense.”
Oh, this is good.
But this is the one I’m more likely to remember.
“That’s nonsense”, eh? Well as a rejoinder that’s pretty quick and easy.
Like your mum.
There are dozens of popular beliefs that would make me want to just say, “That’s nonsense” – Things I’ve researched once but don’t have ready refutations for… so I have some sympathy for that response.
The best rejoinder I can think of is, “It might seem that way, but if you get a chance you should check it out on Wikipedia. It’s really kind of interesting.”
If you really want to deal a knockout blow you need to pull out a fallacy with a Latin name, forcing your opponent to Google it and impressing any audience with your erudition. This seems like a particularly apposite one, it means precisely the rejection of an idea as absurd without addressing its merits.
It has a nice anecdote behind its name,
It is quite difficult to make sense of.
I can explain it for you but I can’t understand it for you
But just be careful not to go anywhere near the old trope about them dismissing Galileo as crazy, because then your opponent can hit you back with a Carl Sagan quote, and that trumps pretty much anything.
I’ve tried responding in kind. Satisfying although not effective.
I’m going to remember this one. 
A simple “how so?” usually works fine.
“Nonsense THIS!”
*turn over the table and flying back kick their face.
Feel free to say I told you to do so in court.
That’s the prettiest thing I’ve seen or hear this whole day! Thank you!
Good one!
How about, <nodding slowly> “People with your limitations usually think so at first.”
Either “why do you say that” (ball back in their court), or, “I thought you’d say that.” - back on the defensive. Depends on the situation.
