Scissor Sisters singer Ana Matronic has shown her suppport for a campaign to end violence against lesbian women in South Africa.

In an emotional video made for Amnesty International's Write for Rights campaign, the US performer has spoken out against the plight of 24-year-old lesbian activist Noxolo Nogwaza who was raped, beaten and stabbed to death in South Africa in April, 2011.

It is believed she was attacked because of her sexuality and Nogwaza's killers have yet to be brought to justice.

In an emotional video made for Amnesty International's Write for Rights letter writing campaign, Matronic speaks of her own experience growing up in an eccentric family and her flamboyant career from female drag queen to chart-topping band member.

'It is my dream of dreams to have everyone in the world be unafraid to be who they truly are and are able to express themselves,' a tearful Matronic said.

'I believe we should accept people for who they are. One woman, Noxolo Nogwaza, a 24-year-old lesbian gay rights activist, was raped, beaten and stabbed to death for believing the same thing.'

Nogwaza was a human rights defender who campaigned for lesbian, gay, bisexual, transgender and intersex rights in South Africa. Now EPOC, an organisation she was involved with that works to combat hate crimes, are campaigning for justice.

In recent months, South Africa has seen an upsurge of what appear to be hate crimes, targeted at people because of their perceived sexual orientation or gender identity. This has increased the levels of fear amongst LGBTI people in South Africa dramatically.
