On a serious note, I believe that it's unethical to eat animals. But personally I am not willing to get out of my comfort zone and I plan to continue to eat souvlaki for a long time to come.
The thing with vegans, other than being extremely annoying, is that they pretend to come from a high moral ground when engaging in a shit ton of activities (excluding eating meat) that directly or indirectly involves the death of a shit ton of animals. Sorry, unless you live in a cave or a forest consuming the least possible resources needed for your survival then you have no right to claim you are better.
