If I was sitting opposite you in a pub for example my two words would be “Psuedoscientific bollocks”, or perhaps if I had only just met you I might be slightly more polite and say in three words “thats your opinion”.
A more wordy response might be something like “the relationship between practical and empirical science is seldom comfortable; but there is mostly a broad consensus within practical contexts that there should be informed evidence, but there appears to be little agreement about what that means in practice,” when I had time to think and be really polite. Of course that is also just my opinion.
