The expressions “animal rights” and “animal liberation” have both become unfortunately associated in a large part of public opinion with what the public considers, rightly or wrongly, terroristic tactics, intimidation and violence.
A Google site search of many media websites will reveal that this is the case: “animal rights” will come up almost always followed by “terrorists”.
“Animal equality” is perhaps a better name, because it encompasses all the internal, sometimes little more than semantic, differences among the various philosophers, activists and organizations who are, after all, fighting for the very same cause.
These distinctions may appear more important than they actually are. For example, moral philosophers of different schools of thought might provide different justifications to outlaw human slavery, but in the end they agree on the most fundamental principles.
Something similar happens within the animal equality movement.
