The humor you are seeing is what is known as grim, or dark, humor. We don't like killing animals anymore than the next person...it is definitely on my list of least favorite things to do. This thread is about folks who try to make us feel bad about our choices, just as you are doing right now.
We are not laughing ruthlessly about killing a lesser animal than we...we are just a little tired of having to justify it to those who take no responsibility for their food. They like to enjoy it without the tough choice of having to personally kill it....their choice, of course, but it still irks me to have to listen to how cold-hearted I am because I have the guts to stare my food in the face before it dies.
You don't like hearing how animals have to die so that we may live? Well, flip that coin. We would prefer NOT to hear the little digs and comments about how chickens are friends and not food. I have human friends, I have chickens to provide food for my family. When they are in my care they are given a good life...and then a good death. This is right in my world. Just as your keeping your "friends" until they die of old age is yours.
It doesn't take much on this forum anymore to offend someone. Everyone wants to be offended by something nowadays, for some reason. It's simple....don't like what you read, read something else. It's what I normally do. If you like to pick a fight every time someone expresses an opinion, then it's likely you will be fighting on here all the time because opinions fly like flocks of birds here.
