You are either vegan or you aren’t. There is no “semi-vegan”, “flexi-vegan”, or “almost-but-not-quite-vegan”. Veganism isn’t a diet, it’s a belief system and a lifestyle.
If you choose to use animal products you aren’t vegan.
Choosing to buy fur means you aren’t vegan. Choosing to eat the “occasional” animal product means you aren’t vegan.
