Yes. First there is nor "rule book" anywhere that anyone can point to that dictates what a vegan "can/cannot" eat. Second, as one pedantic vegan points out, part of the definition is "as practical as possible" when it comes to avoiding animal products. However, kids and fanatics like to dwell on absolutes because it preserves their cool "hey look everyone I am vegan" bragging rights.
It's your life, your rules. who really cares what other people think. You are a vegan. Good for you.
