Genetic Fallacy

Logical fallacy

Judging a claim by where it came from rather than by whether it is true. The origin of an idea is not evidence about its content.

An everyday example

“That figure came from a tabloid, so it must be wrong.”

The same move in this debate

“Veganism is a modern fad, so its arguments don't hold up.”
