I started off to make a comment responding to this, but found far too many issues:

• Statements that were purely false (veganism started in 2010?, "plants contain anti-nutrients" as though it was all plants, vitamin/fatty acid deficiencies, kids suffering from not getting growth hormones from their food?)
• Lots of composition/division fallacy
• It doesn't sound like you were using source material for much of this information (you keep saying things like then I heard, then I read, then so-and-so told me)
• A whole lot of generalizations and "as a vegan" statements that are not true for many/most vegans...

So, I'll be making a full post in response to this. Thanks for the inspiration!
