Every social difference does not lead …

Not all forms of social differences lead to social division. It depends upon the social circumstances and the combination of social differences with other form of differences. E.g. combination of race and economic backwardness would constitute social difference leading to social division. However, it varies from place to place. While language or region may be a form of social difference leading to social division in one society, it may not occur in another society due to different prevailing conditions.

 Taking the example of several countries we can explain it -

1)India is a large country where different people from different places live together...

2)similarly, Belgium is a small country where different communities live together.

3)Even some homogeneous countries ie, haing the same community, religion people, are undergoing rapid change due to migration of people from different countrie and communities ..

4)The people bring with them their own culture and form  a community of their own there ..

5)Thus we can say that every social difference doesnt lead to social division.
