Can you please help me think of the better words for activities that join people together or bring them apart? Thank you

To be specific, this conceptualisation enables different types of activities (connecting or disconnecting) in a multiethnic community to also generate different types of multiethnic solidarity, that is, different types of understanding and behaving towards members of different ethnic groups.
If I were in a jocular mood, I might suggest 'cleaving' and 'cleaving', but a better choice would be 'cooperative' and 'divisive'.
Emotion: smile Thanks.
