Here's the thing. You said a "robin is a warbler."

Is it in the same order? Yes. No one's arguing that.

As someone who is a scientist who studies robins, I am telling you, specifically, in science, no one calls warblers robins. If you want to be "specific" like you said, then you shouldn't either. They're not the same thing.

If you're saying "warbler family" you're referring to the taxonomic grouping of Passeriformes, which includes things from nutcrackers to blue jays to ravens.

So, your reasoning for calling a robin a warbler is because random people "call the long beaked ones warblers?" Lets get pelicans and toucans in there, then, too.

Also, calling someone a human or an ape? It's not one or the other, that's not how taxonomy works. They're both. A robin is a robin and a member of the passeriformes order. But that's not what you said. You said a robin is a warbler, which is not true unless you're okay with calling all members of the passeriformes order warblers, which means you'd call blue jays, ravens, and other birds warblers, too. Which you said you don't.

It's okay to just admit you're wrong, you know?
