"It's cool and awesome" that a product WHICH PRODUCTION INVOLVED ANIMAL-TESTING exists…
So, do not call yourself Vegan; you are NOT. You are plant-based, but you are NOT Vegan.
Vegan people do NOT touch stuff, which production-process involved testing on Animals – be it shampoo or burger, toothpaste or, well, anything else.
You cannot even use the NON-valid excuse "but it is important to have plant-based stuff which is enough meat-like, so the sacrifice of 'just a few rats' is fine" – there IS the Beyond burger, there are more kinds of stuff currently being developed (like a 3D-printed burger!!), so, even THAT lame excuse does not hold. However, even had it not been the case, STILL it would NOT have been justified, NEVER. Had you been a REAL Vegan (and NOT merely "plant-based" faked vegan…), it would have been obvious to you, too.
It is a sad thing you choose to behave just like any other carnist (and I can already see them defending your actions here…), since the Vegan community NEEDS your voice. We NEED rational and sane people, fighting against all the pseudo-science quacks. But, regrettably, you are just not it.
