I only focus on people that I think are able to make the change, have enough self confidence to stand up for themselves and enough independence to keep them on track. I think veganism is a 1000 year project but I am not as much of a doomer as bee, I think we need dedicated people to make vegansim seem possible and attractive who will be the vanguards of the inheritance of civilization. Abolition of slavery is still a work in progress but it has changed in the past thousand years and the animal of human exploitation of animals will occur on a similar timescale. So for me it is still worth while to not own slaves and not exploit animals and can show others that it is possible.
