Vegans mistakenly believe that it is wrong to kill living things, and this only applies to animals, birds, fish.
Reply:
If a person is vegan because they think it is more healthy for them, that is their business.
But pushing this agenda at others is hypocritical.
Why is it hypocritical?
Every living thing (biological entity) feeds off other living things (or their remains) to live. This includes animals, fish, birds, reptiles, plants, trees, insects… etc.
If a person believes that feeding off other living things is wrong, then they must realize that they are fighting nature, and that anything that does not feed off of other living things will die.
Plants, fruit, berries, nuts, trees, etc., are also biological entities, which means no matter WHAT you eat, you are killing something to eat it.
Thus, this urban myth is not factual, invalid, incorrect thinking.
