An interesting paradox I have notice is that, much of the "nice guy" rhetoric women put out, regardless of what everyone considers a "nice guy"(don't want to start this debate here), is a form of virtue signaling. It's an ideal desire that's stated to raise or level one's social standing, or for a woman's sexuality to seem virtuous.

This is because, "nice", has no consistent meaning when applied to men. Women can think all sorts of different kinds of men are nice. It's not a true quality, just a virtuous label.

The male equivalent of that behavior is when guys say "I like girls with no makeup on" or "Girl's look better with no make up on". This statement, like the nice guy one, is complete virtue signaling. It's a dishonest attempt for a guy to sound noble or gentlemen like, but not reflective of what he really thinks.

Does this mean no women are attractive without make up? Of course not! Many are. But the idea here is women are more attractive without makeup then with it. This is almost never true,

Example 2

Example 3

As a whole, women aren't getting less attractive when they put make up on.

Men say this primarily in fear of sounding like a pig or being accused of being shallow, primarily why women do their equivalent.
