Animal Liberation = Earth Liberation = People Liberation
It is simple as that.
They are all interconnected.
Oppressing another is an expression of power over a group or individual.
So, it is not about whose oppression is worse, that only serves to keep people separated and fighting amongst themselves, instead of building alliances and support and connections.
Seeking to liberate one group by oppressing another is still oppression and not freedom, it is simply exploitation by another name.
And people of an oppressed group, shouldn’t turn around and oppress others, or they will never be free themselves.
All are free or none are free.
