Appeal to tradition:

Emotional/Evidential Fallacy

Definition	Example
When a claim is deemed true on the basis that it has a long-standing tradition behind it.	Polygamy is wrong because marriage here in our country has long been only between one man and one women.
Notes
All traditional practices were at one time new. The duration of a practice neither validates or invalidates the practice. Patricide, child sacrifice and self-immolation were all well-established traditions at one time, yet are now generally abhorred.
