I was a child cancer patient (non-hodgkins lymphoma) who directly benefited from chemo drugs tested on animals.
I have thought about this long and hard, and if I had a choice when I was diagnosed at 12, I would have refused. But this was the early 80's, and it wasn't in the public conscience as much.
I can't, in my own good conscience, support this kind of animal testing.
I do not speak for others, only myself, so perhaps you should speak for yourself, and not worry about what others do or don't support.
