You missed the point entirely.  If one thing in the world has a negative, we don't all focus on that one thing.  However, since there are many things in the world that are in the negative, as a varied community expanding across the planet, we have the luxury of choosing different things to focus on, at least, to aid in. 

So there are millions of people who need help, so are you saying that the people who are willing to help should ONLY and SOLELY help those millions of people and forget about everything else that needs our help?

That logic is too narrowminded and inflexible.  First, you have to realize there are already people helping the less fortunate.  There is a vast diverse selection of people in various causes - either that be for human rights, animal rights, environmental issues, and so on and so forth.  So to fit in with what is closest to our own interests, experiences, and reach, we will choose the form or organization most suited to our own desires.

You talk about altruism towards animals, but you fail to mention altruism towards humans.  If you don't like to help others or to help a cause, it would not benefit you anyway if you had kept your mouth shut.  Yes, you have your opinion and you have the freedom to say that opinion, but you just wasted 15 seconds of your precious non-altruistic aka selfish reasoning to a thread such as this.

So leave this message to those that care, that wish to make some form of positive difference in the world.  It does not benefit you whatsover to go against it.
