If half the population is christian the other half is probably also not completely oblivious to what that other half understands by family values.
I think the best way to overcome this "dog whistle" problem is to appropriate it and steal it. "Family values" -- "good, we want to have gay, transgender, happy and safe families and we love our family values".
"Diversity of thought is more important?" - "Yes it is, and we find that people of different ages, races, genders, nationalities, educational, social and economic background end up with the best diversity of thoughts and ideas so we go out and actively recruit accordingly". What I see tech companies doing is being very vocal about diversity then turning around and recruiting young white men from a few top universities. Or saying women should be equal but then paying them less. Or covering up harassment and abuse (thinking of Uber here).
