I always think it's really obvious, from my behavior, but maybe I'm less transparent, than I thought. That's a relief.

That's usually a symptom of the eyes of the beholder.
Disingenuous shrowded people tend to project themselves onto whom they're observing.
I think the feeling of "transparency" can be subjective. Everyone is different. Different motivations. SURE, some groups and categories of people exist.
But if they can be lumped into a category, they probably wouldn't be conversing with you as I've noticed over the last few years, your perceptive ability (even through text) is quite astute, and you're no sucker for people who can't contribute to your mental stimulation. You tend to simply drift, politely from those sources.
Almost a disregard.
