For all his WASPy clean cut preppiness and Christianity he could give a word or two in support of the civilized part of that world. It wouldn’t be virtue signalling if it was heart felt. But by his silence he shows he doesn’t give a shit and possibly worse. And speaking out by people does make a difference. Words of courage and support can influence others and lift up people that feel like the whole world is against them. And it can rally others to speak out against evil and to take action.
Okay. If that's the way you feel.
I don't. To me his words on this subject don't matter.
But I'm not really sure what his "WASPy clean-cut preppiness and Christianity" has to do with your concern about fake and shallow virtue signaling -- or lack thereof.
Sounds like you've got a dislike for his looks and his beliefs.
