Well, when you put it that way...
Not going to speak for those you quoted, since that's not really my view, anyway. But I'm also not discounting the very real possibility that some can, at the very least, "blend" sometimes -- meaning, they don't personally catch my attention at a certain time in a certain environment (while others might read them just moments later). I'm pretty darn observant, but even with that I realize I can't or don't always get a good look at every single person among a crowd. Or, perhaps it's not fully-lit. Or, maybe I'm just in a big rush or I'm preoccupied with something, and only catch a split-second glimpse from the corner of my eye. Or whatever.
So, do I miss them sometimes? Perhaps. Who knows. Obviously they're not easily & instantly catching my attention in those situations, anyway.
But this definition of "blending" can be quite different than actually "passing."
As mentioned above, the only one in the real-world who has *passed* with me, as far as I'm concerned? I didn't speak to her, which may or may not have tipped me off, but I was checking her out pretty hard & for quite a while, LOL. Never once did I suspect it was actually a CD'er -- I honestly thought it was a hot GG. She did a great job; she looked awesome. And for the record, it was at a fairly-lit hetero club on Halloween, and she was sitting at the bar talking to some guy, so I wasn't really expecting that there, anyway. And no, I didn't have my beer-goggles on. Finally, I didn't believe my friend at first when he told me... but I knew him well enough to know he wasn't BS'ing after I kept pressing.
I bet she "fooled" a lot of guys that night. And probably lots of other nights, too.
