What a remarkably pointless and silly thing to say. It's like the "I'm not a racist, I have black friends" crap - you evidently have some pointless gear prejudice and are now imagining things as a result of it.

And it'd still be a completely pointless observation because correlation does not equal causation. In such cases, pointing out these kinds of details is not only unnecessary, but makes it look like you have some kind of axe to grind.
