Great job! Was this for school?
I think something to remember when fighting for animal rights, is that historically, people have achieved freedom through still being looked upon as "not as smart", or in many ways inferior.
Thomas Jefferson (US President) fought to abolish slavery, though still believed blacks had "less mental capacity" than whites. He just didn't believe brain power was a credible excuse to deny them liberty.
Though obviously he was wrong, I think it's a great example for us of the animal rights movement. While animals are obviously not as intelligent as we humans are, that is not an excuse to deny them freedom -- they still suffer, long to live, love, shun destruction and death etc.
We really can do this. Viva la revolution.
