I love that you can get all the taste without the violence and suffering. Eating is not always a single-person activity, so having vegan substitutes for meat and cheese is great when eating together with non-vegans who may be wary of falafels.
There are very few vegans who are vegans because of taste. Many are worried about the environmental impacts of mass animal agriculture killing trillions of animals every year.
The most prominent and outspoken animal liberation advocates — Ali Tabrizi and Ed Winters come to mind — are strong proponents of vegan-dairy, vegan-seafood and vegan-meat. It really doesn't make sense to call those people "pretend vegans". Check their talks and films[0][1], they aren't "making a joke of the whole idea of being vegan".
I don't get why carnists place such importance on real suffering and real death. Is it not real Adidas shoes if it isn't made by slave labour or something? Is it not a real car if it's not guzzling diesel? Why not cut down on causing harm when it's so easy? I don't get it.
