It is important to recognise that social constructs are powerful - but they can, and should, be challenged.
There is currently a good deal of contestation over what "veganism" means in the 21st century. It seems that much of the original vision and scope of the original vegan pioneers is being erased in favour of a more limited, business-friendly, definition.
Any thinning or blanding-out of the concept of veganism should concern modern-day ethical vegans who take an expansive view of what veganism does and could mean. This is especially true when we learn that there is at least one government-funded vegetarian organisation whose operatives speak at vegan and "animal rights" events suggesting that vegans should "tactically" eat animal products (and not be too picky about that possibility), while "strategically" limiting the vegan movement to be just about food.
