If you want to be vegan, more power to you. But please talk to your doctor first (and optionally do a bunch of reading from non-specifically-vegan sources about how the food is grown). The nutrition-feasibility, health benefits, and current, real-world environmental impact are frequently and loudly lied about by vegans.
I’ve been vegetarian for 20+ years and have recieved nothing but love and support from vegans. Even one person I knew that was so committed she changed her last name to Govegan. I did recieved some chastisement from a plant based person for not knowing the difference between plant based and vegan, but they were also very anti-vegan.
