You don’t have to be a rampant vegan animal lib militant to take up the cause against vivisection. This is a needlessly cruel UNNECESSARY practice that anyone with an ounce of humanity about them should revile from. But mumbling “that’s disgusting” isn’t going to change the situation.
Declare yourself on this issue and protest where you can – even if that’s simply by raising awareness by wearing T-shirts like this one, or taking small personal actions, like boycotting products made by companies that are known to test on animals and letting them know your attiude by email or letter.
And on a related issue, buy free range eggs and meat only. Battery farming is an abomination as appalling as vivisection. Besides, free range produce is far better quality.
