That's not the point though. If you tell me you're vegan and then drink tea with milk in it, you're not vegan, you're just pretending to be. Doesn't matter if you can argue "well me drinking this tiny bit of milk doesn't change the dairy industry", you're still not a vegan.

I'm not blaming consumers for the current state of affairs. I'm blaming protesters for being hypocrites. There's a world of difference between the two.
