Deputy prime minister and leader of the Liberal Democrats, Nick Clegg, writes for PinkNews.co.uk that Peter Tatchell has never allowed physical or verbal attacks to bully him into silence.
Peter Tatchell has been a tireless campaigner against homophobia, racism and sexism and for civil liberties and social justice.
In standing up to and confronting injustice and abuse, he has often put himself at a considerable risk.
Although his campaigns and tactics have often courted controversy, no one can deny the positive impact that Peter has had on our society and the importance of his role in fighting for LGBT rights.
It is a tribute to him that the unpleasant verbal and physical attacks he has suffered have never bullied him into silence.
With that, I want to wish him a very happy birthday and I hope that his activism will long continue and bring many more successes all over the world.
