You would think that when people adopt Christianity it will bring communities closer together, strengthen families and marriages but why is it that..

in every society which Christianity is being adopted as a mainstream religion, the opposite is happening? Examine any society where Christianity has been adopted in the 20th or 21st century. Before Christianity, the men were hard working family oriented, wives and children were respectful and the families were closely knit. After Christianity the children started becoming disrespectful the wives became irritated by their husbands, and the husbands no longer made his family a first priority. As a result, communities fell apart.

Why does Christianity do the opposite of what it's intended to do and why do Christians do the opposite of what Jesus taught?
