Re: Crew of the Enterprise-D
If both parents are on board, and one is a crewmember, that is a hundred civilians
There are also unattached civilians aboard the Enterprise, like Keiko. Not married to Starfleet (at first) and with no children. I usually consider Keiko (and people like her) to be aboard as a civilian contractor of some sort.
The teachers in the school perhaps too.
It's easy to support someones beliefs if they are identical to your own.
Tolerating beliefs that you don't personal embrace, or even fully understand, is harder.
