There's no reason to assume the "white guys in their 20s and 30s who work at Google" don't fly their freak flags every once in a while. Whether or not sharing flags present a risk of trust and why it presents a risk of trust is the real issue to address here.
I'm not sure you grasped his point. He wasn't saying "white guys never have anything to fear".
He was addressing his remarks TO skeptical white guys who feel they have nothing to fear, by asking them to consider what life would be like if they weren't white people with harmless opinions and positions of privilege. The way an argument is framed often determines whether it will be listened to.
I'm not saying we don't fly our freak flags, I'm guessing the guy I was directly responding to does not really do so if he doesn't see the big deal if G+ (and identity in general) is forced on the internet
