This is precisely the kind of attitude about veganism I am always trying to shirk off with my book & blog. For some, you can never be "vegan enough." I have no ill-will against this poster, but I'm using the comment as an important example. It is perfectly fine, if you have an interest in veganism or alternative cooking, that you do what you can when you can and not feel bad about not being able to conform to the impossible standards of the so-called "pure tier", the criterion of which is inevitably determined by unforgiving adherents to a certain dogma.
These people usually have the extraordinary means of supporting their lifestyle that many may not have the privilege of enjoying. It is perfectly fine to be fundamentalist about your beliefs (eating or otherwise!), so long as one does not assume all people have the same ability/financial means/goals as oneself. Not only is this criticism unfair to those trying do what they can, but it is also petty and does nothing to serve anyone's purpose- it alienates.
So, please! Keep the message of healthy eating alive and well. Be vegan because you WANT to be, and encorporate what elements of the lifestyle you can into your own life with positivity.
