I strongly disagree – as a person who's eaten vegan for over a year, tried all the fancy meat alternatives, and has gone back because a good grass-fed steak is just 10x more delicious.
If folks go vegan, go full vegan and accept permanent change in your life, not some desperate half-assed attempts to change as little as possible, which don't seem to work. That's valid for any diet, or any other change in life.
Ie I eat beef steaks maybe once a year. I can really appreciate them, but its just not something that I feel should be part of my frequent diet, can prepare tons of other tasty stuff that are lighter on meat. Control a bit your emotions and understand where they come from, and you can be happy as a clam with any diet.
