Ok, that I can understand, but using the dramatic/exaggerated terms you did (knowing most people eat meat) and bringing it up to a bunch of people you don’t know in a forum still seem that you were trying to stir up emotion or even offend. The fact that you use such extreme words for it when it makes it sound like you are saying that it is immoral. (even though that doesn’t coincide with Church teaching on the consumption meat) In the Old Testament God called for animal sacrifice and even made rules on how to slaughter animals.
I am not so upset that you brought up the issue and your experience, but using such dramatic terms seems you are just trying to evoke anger, disgust, or pick a fight. Most people eat meat and even love it. They associate it with their favorite family meals, bonding with family, (especially around this time of year) holidays, culture, tradition, ect. It would be like me coming in to a room knowing some have Polish ancestry and saying Polish tradition is disgusting. It is bound to upset some people using such strong terms that are connected with something near and dear to them.
