Wow. Honestly, you're starting to sound autistic. Do you not understand that comparisons include the possibility of contrasts? A comparison can draw out similarities and differences, while a contrast emphasizes the differences, and may be still be called a comparison. The latter comparison would amount to a failure to find enough similarities to regard the two things as being overall similar or comparable.

Call it what you want, then, but strictly speaking I've been drawing only a contrast between economics and the natural sciences. By contrast (again), you've been practically equating the two. You've been saying those disciplines are overall more similar than different.

I mean, this is flat-out hand-holding now. I don't know if it's trolling or autism or what, but it's boring.
