I'm in the fortunate situation where my closest family would trust my insticts if it came down to that. However, my parents, sister and further family would not accept me ranting on about these subjects, so I'm keeping silent for now.
I try to secretly incorporate some ideas into them though. I use easier to "prove" or more likely subjects as a way to make them aware that not all must be like it seems.
I can understand how you feel ophiuchus, as this is matters not lightly taken by everyone.
Most people live in a bubble, and like small children with their balloons they may get upset if we pop them.
