Personal example. A friend mentioned that a new hire at her work didn't have to go through as much interview training as her, and she was wondering if she should take offense. If she were a guy, I would have said something along the lines of "come on, 'amount of interview training' isn't a real status marker, you're getting worked up over nothing". But I strive to be an effective communicator, so I couldn't just bluntly refute her feelings like that; it'd sound like I'm denying the very real ways that women can be subtly mistreated in the workplace. Instead I clammed up, and she ended up deciding to file an HR complaint, which is unlikely to have a positive impact on her career.
Is there any way I could have told her what I thought without being misunderstood? Sure, maybe, if we'd had 30 minutes to sit down and talk about a bunch of abstract principles. Is there a strategy that would have fit inside the 30 seconds of conversation we had on the topic? I don't think so.
Of course the problem with this is that the facade will crumble at some point because the person doesn't exist.
What about: "I personally wouldn't have cared about that." -- then you didn't say what you thought she should do, instead just what you yourself would (not) have done.
And she could have used that as a data point when making her own decision.
And, optionally continue with: "you got more education than X, I wonder if that might as well mean that the company decided to invest more money in you, maybe a good thing for you. Maybe X could have filed a complaint about that as well"
