They are correct because veganism in isolation defeats the purpose for which it is intended.

Wow, that hit like a freight train for some reason.

There are some excellent points brought up in easily understood ways. A few of my favorites -

We understand, contrary to mainstream perceptions of us, that wanton destruction and violence will not bring about the end we desire. … But we also understand that we can make room for free creation only by obliterating that which exists to prevent our liberation.

It is we who are the enemy; overthrowing the oppressors in our heads will be the revolution—watching their constructs fall in the streets will merely be a (joyous!) sign that we are revolting together in a unified, unrestricted manner.

Governments and international economic organizations carefully manipulate food and water supplies to control entire populations.

The vegan must go beyond a monist understanding of non-human oppression and understand its roots in human social relations. What’s more, she must also extend her lifestyle of resistance to a resistance of human oppression.

Because power is a social concept, we as people do not necessarily comprehend what it means to us.

Lines are drawn without care but with devious intent, and we are engineered by the institutions which raise us to believe that we are on one side of the line, and that the line is rational to begin with.

There are many more, what a great read. Thanks for sharing!
