Personally, I've never thought of "vegan" as a political term, rather just as a description (a person who does not eat animal products of any kind). However, that's just an argument over semantics.
There's more to veganism than your description. I am not against a vegetarian diet, if it is called for, but veganism is a different matter. It tends to both political and religious quirks - a philosophy that rejects the commodity status of animals.
A vegan is one who won't wear leather or fur shoes or clothes, or won't tolerate beeswax candles.
Veganism is not Christian. God gave us animals for our use and benefit.
