I grew up in this position, my family being exactly the spineless individuals you describe... (with the exception of my dad).
... after my dad died, I haven't spoken to any of them.
Standing up on your own and not being scared of telling your truth, is kind of a default setting for me.
...It's definitely not a group activity, in my experience.
lol
Good stuff. We can stand up for our conviction and be wrong too ;) But at least we speak up.
