Vegan Circlejerk

Start by not making it appear to be activism.

Start by presenting options that are as appealing as options that have animal products and cost less than animal products. Make equivalents that have similar flavors and textures so that people aren't experiencing a significant shift when they're eating, because food is often very emotional for people. (...Which you demonstrate so aptly in your activism against animals as food; it's an emotional issue for you, even if it has intellectual aspects.) You need to create conditions such that people can eat less meat, and titer down their consumption, without attempting to shame them while they reduce their consumption.

There's a restaurant in Atlanta that I highly recommend called La Semilla; they do Cuban food, and the entire restaurant is vegan. They understand that if you want most people to even consider being vegan, they have to be presented with food that looks, smells, and tastes appealing, and it must be presented in a welcoming atmosphere. They aren't loud or angry in their message; they're doing good food and being a good example. Every meal that a non-vegan eats there is one less meal made with animal products, and that, sir, is progress. And it's more progress than they'd see if they told everyone that wasn't already a vegan to fuck off and get the fuck out of their restaurant.
