I, and the people around me, mock vegans because 50% of vegans I've encountered are hypocritical.

They don't eat meat or animal products, because of the "environment", but then eat fruit and vegetables that were imported from thousands of miles away by air. On a weekend, they drop pills, the trafficking and cultivation of which costs lives every single day. And never mind their flights halfway around the world for vacation twice a year, which do more to harm the environment than a year of not eating animal products.

Vegans make an earnest attempt who practice what they preach, across their entire lifestyle, have my utmost respect.
