"... to counter the leftist/progressive nincompoopishes arguments."

Should have used a comma after "leftist/progressive" to separate the 3 adjectives.

Let me correct it and tell me if it's still wrong.

First off I should not have made nincompoopish plural.

"... to counter the leftist/progressive, nincompoopish arguments."

All three adjectives, leftist/progressive and nincompoopish describe the noun arguments.

How does it look now?

I don't belong here.

I don't understand grammar.
