Would you consider it misogyny if someone mentions gold diggers in a conversation about dating? Or if they talk about gold diggers in any context at all? Or if someone even acknowledges that gold diggers exist?

Because a lot of people would consider that misogyny.

But an instagram model openly being a gold digger lends credence to the argument that "some women are gold diggers."

So if you consider it misogyny to acknowledge that some women are gold diggers, then a woman being a gold digger is, by your very definitions, creating a pretext to justify misogyny.

(Funny how women can generalize about men, but when men generalize about women it's suddenly a problem; or even if they don't generalize but cite specific examples, people will still make a strawman argument about them generalizing so even that's bad).

don't know how else to interpret that.

It involves assuming the point of view of a misoginist who feels entitled to be misoginistic. I know it's not a position you thought you'd end up when you woke up this morning, but trying to understand what's going on in other people's head is a first step towards fighting intolerance.
