So, you are saying that you have a friend with a career like above that you don't like and you want to threaten a family member with harm if they don't quit their job???? No, that is NOT acceptable. With your given examples, abortion is legal, right or wrong, not everyone believes the same thing about abortion. A scientist that works on animals, a LOT of people would be DEAD without that research, sorry, can't support you on that one. The stem-cell researcher, there are a lot of places to get stem-cells other then aborted fetus'. I am very supportive of scientific research for medical issues. Furrier, again, not everyone believes that wearing a fur is wrong. Personally, I have no feelings one way or another about wearing furs other then I think they are ugly and I wouldn't want one.
What makes what you are doing, threatening a family member, better then what they are doing in your mind?
