"Kind" or "Kinds"? [duplicate]

You're one of those spare-the-rod kind(s) of people, right?

In this sentence the demonstrative adjective "those" defines the noun "kind". So it affects this noun in terms of plurality. So it would be grammatically right to say:

those kinds

But to me it sounds better if I hear:

this kind of / that kind of (singular) instead of those kinds of (plural)

So to me the whole sentence would be:

You're one of that spare-the-rod kind of people, right?

where demonstrative adjective "that" and compound hyphenated adjective "spare-the-rod" both define one noun - kind. So 2 words describe 1.

that (1) spare-the-rod (2) kind

So, basically, weather to use plural or singular for "this/that/these/those" depends on the choice of "kind" or "kinds" for this is a semantically and therefore grammatically bound pair.

I would use "kind". Therefore, I would say "that/this":

You're one of that spare-the-rod kind of people, right?
