This debate reminded me of a website I found last year when I was writing about animal testing for an assignment.

My personal opinion? I'm not in the situation where I'm dying and need drugs that have been tested on animals. But I would probably use those drugs to save my life as those animals have already been killed. In the case of life and death, I will choose life.
When it comes to animal testing though, I would want them to stop. There are a few alternatives (human tissue cultures, computer models, human trials and probably more) that can be used and developed and if they are given a chance I'm sure they'd become the norm. However, it is cheaper and 'more normal' to just infect and kill thousands of animals.
I also agree with the preventative method, but we would still need something to help those who are currently living with AIDS. So a 'cure' would still be sought after.
I also found a link for if you want to act:
http://www.globalservicecorps.org/site/donate/. There are different projects that you can donate to; AIDS education, orphanages, veggie patches for AIDS infected people... All positive ways that you can help that do not involve animal testing. I have no idea if they are a religious organisation though, for those who are interested. I didn't have a chance to email them.
