As far as their organizations are concerned, AF and ALF have nothing in common, but their basic statements are similar.
Both Animal Freedom and the ALF declare that animals have a right to freedom, while the ALF thinks that some animals should be literally liberated. AF says that this should be done on a basis of legal actions to end the industrial keeping of farm animals; the ALF says that animals, that are now kept in deplorable circumstances, should be freed immediately, even if that means using illegal methods. The ALF's main concern are laboratory animals and animals kept for their fur; AF's primary concern are factory animals kept in industrialized animal husbandry methods (factory farming).
Another way to express the difference is that AF's main interest is passively mistreated animals while the ALF mainly deals with actively mistreated animals. That is why the people of the ALF sometimes are in somewhat more of a hurry.
 

The reason for AF to stress the fact that Animal Freedom wants to use only legal methods, has to do with the expectation that:

  1. Activists exchanging ideas and working together can develop many legal methods;
  2. Once that factory farming is banned, a gradual put to a stop can be organized in less than a year; our aim is not to set farm animals free, but to lower their number and to improve the circumstances of the remaining livestock.
  3. The chances of factory farming becoming banned become greater when there is more public support.

     
Animal Freedom thinks that its considerations and actions are honorable and are shared by many people, and can therefore best be made public. We exchange effective ideas about legal actions for animal rights and against factory farming; we advocate ecological farming; realistic (higher) prices of animal products with all reasonable costs included; the ending of the export of meat and poultry produced in factory farms and the export of living animals; founding animal rights on the same grounds as human rights (i.e. freedom); restoring the natural balance in nature and we organize cookinglessons for meatless dishes.  

We support the Party for the Animals.

The Party for the Animals is a Dutch political party that aims to improve the position of animals in our society. The party was founded to promote an awareness of the way in which humans treat animals and to emphasise that this needs to change – in the interest of not only the animals themselves, but also humans and the environment in which we all live.
