I want to go vegan. I read all vegan questions thread in this sub, almost all philosophers agree vegan is right but no one tries to practice it except Peter Singer and some utilitarian philosophy philosophers. Why?

That's false, there are a whole lot of antispeciesists and vegan philosophers that are not utilitarians, some of those were or are Tom Regan, Christine Korsgaard and Gary Francione.

Edit: Another example, a non-utilitarian consequentialist that is vegan would be Oscar Horta.
