No legit serious vegan would step foot inside Burger King. The 'Impossible Burger' isn't even vegan to start with! https://www.peta.org/blog/why-it-is-impossible-for-peta-to-g...
Obviously, you can ask them to leave that off, but If a food is not vegan in its default configuration, you should probably think carefully about whether they're even trying to achieve vegan compliance.
I do disagree with the vegan crowd, but they are at least moral and largely consistent in their own beliefs so fine by me as long as they stay the F* out of my life.
But lawyers and idiots like this really tick me off and I hope they have to pay court costs for this frivolous lawsuit and I hope BK does not pay them off one dime.
