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.
