The chronological snobbery fallacy

“

The form of the chronological snobbery fallacy can be expressed as follows:

1. It is argued that A implies B.
2. A implies B is an old argument, dating back to the times when people also believed C.
3. C is clearly false.
4. Therefore, A does not imply B.

That clearly does not follow.
