This is excellent. We really need to train ourselves so that we have those catchy "10 second" soundbites of truth. It's a real skill to bring up this topic in a way that quickly captures attention and moves the conversation to what we can do, as stated above ..not eat animals... and do it in a way that does not sound like we are condemning them.
I really need alot of coaching with this, but one of the things I let people know quickly when I can and the issue is about to be dismissed is that I used to be a big meat eater "macho meat eater" and laugh at my friend who ate sprouts, calling it grass, then I ended up eating grass! Usually this cuts the tension and they laugh. Then I slip in some health benefit I get since I'm vegetarian or something about as a kid never wanting to eat animals.
Does anyone want to make up "quick scripts" we can use to help give people a moment of pause? i.e. different ones for different opportunities which arise to bring up the topic?
