Seems a valid point to me, but this is the same Federation that sent ships into battle against the Borg with civilians and families on board.
There probably wasn't enough time to transfer the families onto a space station or a planet. The Borg were rushing to Earth in BoBW, and the Starfleet was gathering everything they could for a final defensive at Wolf 359. I think it's understandable what happened.
I think when the Starfleet DID have time and they know they will be going into battle, they have the families transferred someplace safe like the U.S.S Odyssey moving its families onto DS9 during the the first battle with the Dominion. I imagine families were no longer on the Starfleet ships during the Dominion War.
