But as they chose not to arrest her, this shields every other woman who might want to say similar. The argument being: if JKR can say a man is a man with impunity, then why can't anyone else?

The people who wanted JK Rowling arrested knew her views and comments are legal. If the police arrested her and she won in court, that would set a precedent and invalidate any attempt to use that legislation to prosecute people with similar views, which activists were hoping to use it for.
