Re: Question about subjunctive
The subjunctive is used in a couple different situations.
One is the unreal condition. That's the if, as if, if only, I wish, etc.
That takes the "were."
I want to be rich, but I'm not: If I were rich.
He pretended to be angry, but he was not: He really fooled that guy when he acted as if he were angry.
The other is that category of demand, require, insist, etc.
That takes the bare infinitive.
I insist is be seen at once!
She demanded he leave.
You can't treat both types of the subjunctive the same way. I am not well-schooled in the subjunctive, so I don't know why they are both called the same thing. They feel very different to me, and if I got to name them, I would choose different names!
(There may be other types too, and I'd be happy to learn or be reminded of them as well!)
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
