I believe the planet is on a path toward kindness, but every individual's path is different.
Some people get off the path and get back on; some people get off the path and stay off for the rest of their life. Some people move in two directions at the same time.
You can't encourage kindness by indulging in cruelty. Vegans (or whoever) who criticize someone else for lacking concern for sentient beings are replicating the problem that they object to.
Incidentally, what Cyrus describes as an Omega 3 problem may be something else (e.g. a B-12 deficiency). Although in theory a vegan diet can be as healthful as any other approach (or more so), it is often tricky to supplement methodically.
