Use of "these ones" or simply "these"

To my knowledge there is no such rule.

AnonymousWhat is the rule of grammar that makes it improper to say "these ones"?

This rule:

It is improper to say "these ones" or "those ones".

It's apparently only an American rule, not a British one, but even those ones who speak American English don't always obey the rule.

It's either these or those with is already plural adding "ones" is bad grammar. I was taught American grammar that adding "ones" is bad grammar and would have flunked that test. I never heard anyone say that, these ones those ones, in all of my schooling until I joined the workforce and was appalled like where did these people go to school.
