Re: But on the other hand...
Beef burgers, pork sausages and dairy milk are animal products.
Last I checked, having a veggie burger doesn't change beef burgers from being beef burgers. Pork sausages still exist and having Linda McCartney Veggie Sausages doesn't change that.
It doesn't damage the "meat" market having those names.
People don't get confused between meat and non-meat burgers/sausages. Saying it is "passing them off" is nonsense. Glamorgan sausages, which don't contain meat, have existed since the 1800s, and people don't confuse them for meat products.
