Mostly correct re: even if true. A motion to dismiss generally assumes all facts in the best possible light as to the other party (so here in the best possible light as to thedefendantyou mean Plaintiff).
It's still quite something to argue that the plaintiff's complaint actually alleges the defendant harassed everyone equally so the specific allegation falls short.
Not really. That's usually one of the main points of a motion to dismiss- if you are making general allegations, but fail to allege the things that happen to you (the Plaintiff) with specificity, that's usually a dismissal.
If you look at the memorandum of law (#32), there appear to be some pretty decent arguments, mostly premised on the concept that the Plaintiff put in a bunch of salacious details, but they don't really add up to a cause of action (because of SOL, because they don't allege that there was discrimination against plaintiff on gender, etc.)
Short version- if a complaint is just "He's a very bad man!" then a motion to dismiss is often appropriate- the complaint usually has to say, "He's a bad man, to me, in this legally recognized way."
We'll see!
