Fanatics end by subverting their own argument. For instance, animal rights activists have some point, and many people feel sympathy with them. But animal rights fanatics do not have a point. They are the sort of people who threaten human beings in their effort to 'defend' animals.

Activists need to educate themselves about the power of crypto currencies like Bitcoin, invented in 2009, and use crypto to leverage the success of their independent media gains to tip the balance of power away from the troika in ways that could never happen by backing a political candidate.

I've been on both sides: the victim and the villain. I was the victimised model, and everything from my weight to my fertility was held up for discussion. And then I was the person that could garner some kind of positive outcome, by taking on the role of vice chairman of the British Fashion Council and becoming an activist of body image.

Over the years, HIV/AIDS activists and their allies have been pioneers in creating new frontiers in the medical establishment. Through their efforts, the FDA drug approval procedures were reformed so promising new therapies could reach desperate patients quicker.

President Bush has a record of cutting taxes, has provided a prescription drug benefit for seniors, has upheld the Second Amendment and remains committed to stopping liberal activists judges who are redefining marriage.

I am an activist and rapper from Afghanistan, and I use rap to speak out and help end child marriage.

It is hard to see Judge Roberts as a judicial activist who would place ideological purity or a particular agenda above or ahead the need for thoughtful legal reasoning.

We know about the socially complex lives of elephants: how they communicate, how they bond, how they even seem to grieve. We have ethologists in the field and activists on the ground to thank for that knowledge.

I don't view Apple or myself as an activist. What we do is for some things where we think we have deep knowledge, or think we do, or a strong point of view, we're not shy. We'll stand up, speak out - even when our voice shakes.

My mother was an activist; so was my father. They came from a generation of young Somalis who were actively involved in getting independence for Somalia in 1960.

Marcus Samuelsson is a chef who inspires me everyday. He has such a deep understanding of flavors and techniques. His food is representative of the diverse world that we live in. What he has done in Harlem with Red Rooster is very special. Marcus is not just a chef, he's a food activist.

It took LGBT activists 15 years to defeat section 28, but this is not a movement that's afraid of the long struggle. They know all progress is hard-fought, that discrimination against any individual anywhere is discrimination against all, and that the campaign for true, global equality must therefore be won one issue, case and country at a time.

We need to be able to guarantee the safety of all artists and activists for human rights so that it no longer takes extraordinary courage to call for a better world - so that every person with the ability to imagine peace, equality, progress, and justice can express their dreams and hopes without fear.

I'm an activist for gay marriage equality and children's rights. I'm the face of Share Our Strength.
