Social Media: A strategy that treats all groups the same will not succeed?

False, you just need to identify that EQUAL = a dynamic, and not a result.

And treating people equally will allow everybody to do 'their' thing, and as long as you protect the groups from getting in each other's way, that should be really successful.

What kind of strategy? If you are talking about a political/economic strategy, then TRUE as evidenced by the former Soviet Union, Cuba, and North Korea.
