@sklaing I've got the same idea about people who generally analyse what they do (be it vegans, environmentalists, the combination or some other variant of thoughtfulness). But I get very, very confused when I meet vegans (there are lots of them/us here in #Umeå) that smoke cigarettes.
Most of those are in it for the animal rights though, rather than the environmental effects or workers' rights. So they don't care about landmasses being used to farm tobacco or the awful conditions the ones doing the farming have compared to what they could have given a fair and equal society.
But then again, I also get very confused about people arguing for gender equality, transgender rights etc. exclusively using Facebook for their Pride campaigns, night clubs etc. (local activists in #Umeå actively support clubs with gender separated toilets by having their events in such places rather than choosing clubs with a higher degree of awareness).
