PES

The Party of European Socialists (http://www.pes.org/) is running an online declaration (Eurospeak for petition) for diversity and against intolerance -

"Our different peoples are what make Europe such a special place. The PES strongly believes that Europe’s success is built on respect for our diversity.
The PES is convinced that the peaceful cooperation that is symbolized by the European Union has no future if intolerance and hatred are allowed to grow in our midst.
We call on all democratic parties - and their European political families - to reject all forms of intolerance and hatred. Everyone has the right to live in dignity and to be treated with full respect regardless of their nationality, ethnic origin, race, gender, sexual orientation or religion.
We call on all democratic parties - and their European political families - to refrain from any alliance or cooperation with any political party that promotes intolerance.
We urge all democratic parties to ensure that their social and economic policies do not generate the social insecurities and tensions that flame the fires of intolerance and hatred."
