Confronting marginalisation

The poems and the song in this Unit allow you to see the range of ways in which individuals and
communities express their opinions, their anger and their sorrow. In class, do the following two
exercises:
(a) Bring to class a poem that discusses a social issue. Share this with your classmates. Work in
small groups with two or more poems to discuss their meaning as well as what the poet is
trying to communicate.
(b)Identify a marginalised community in your locality. Write a poem, or song, or draw a poster
etc to express your feelings as a member of this community.

fight against dispossession? Is there anything specific in the provisions of the Act that allows her to
believe this?
