When I was younger my brother became vegan and he was such a prick about it that he poisoned the discourse in our family for years. A couple of years later I tried to get the family on board with only eating meat 4 days a week to limit consumption for the environment but at that point my brother had killed any good faith engagement and moved out. I am fairly certain that him being vegan has led to more animals being killed because than if he just kept eating meat because he was just too toxic
OP is like my brother. Everyone should ignore him because he is probably twelve and a narcissist that doesn't know that you need to meet people where they are at. The sooner people like him gets ejected from the movement the less damage they will do.
People are saying that they need a car because society has fucked them over and in order for their life to work they need a car. That is why a discussion about what kind of car they should buy to minimize harm is important. OP is basically complaining that the discussion isn't pure enough because only a complete elimination of cars right this second is good enough. They reiterate this over and over in the comments and edited the post to call people "car enthusiasts" because they, like me, think OP is unproductive and toxic to the movement.
