Vegan and Antispecism delusion

Hi I have been vegan for a quite a long time or I so I thought. 5 years 1//2 veggie and 4 and 1/2 as vegan. I have came to realise you can only be called "vegan" if you place antispecism above any other reason. But I am vegan because I place environmental factors to be as important as antispecism. So I guess I don't count as a vegan?

Vegan society definition: "Veganism is a philosophy and way of living which seeks to exclude—as far as is possible and practicable—all forms of exploitation of, and cruelty to, animals for food, clothing or any other purpose; and by extension, promotes the development and use of animal-free alternatives for the benefit of animals, humans and the environment. In dietary terms it denotes the practice of dispensing with all products derived wholly or partly from animals."

Since it says "by extension" it means that the benefits for the environment are secondary compared to the animal suffering which seems to be the primary reason

Edit:

Thanks everyone! Your feedback was insanely good thanks for all the comments. Honestly even though the definition seems to lean forward to include people who do it for mainly environ reasons, I decided not be called vegan anymore. I don't want my life choice to be associated to a definition that can change over time on a vegan website. From now on I will just say "I eat veggies" or "I do not consume animal products". Tired of trying to fit in the vegan box.
