Meats and cheese are like 10 things. There are thousands of edible plants and fungi to choose from. In the overwhelming majority of cases, this sort of argument is just a lazy rationalization so people can avoid grappling with the consequences of their actions.

Most people aren't consuming meat as a necessary evil; they're often consuming it in excess because it's enjoyable, even when they already understand the horrors of factory farming. It's upsetting and frustrating and I just want to do what I think is most likely to improve the situation.
