Veganism is a justice movement. We're not just a bunch of people with some oddball, "hippie" lifestyle wanting people to understand why they should eat more plants.
Carnists abuse the shit out of these kinds of sentiments, in which they neglect the fact that vegan advocacy is not supposed to keep them complacent. The purpose of vegan advocacy is to instill discomfort so that people realize the urgency in learning to reject the exploitation that they endorse on a daily basis.
If you apply this awful framing to any other justice movement, you'd hear people say shit like, "Malcolm X is the reason why people don't like anti-racists!" It just does not make any sense.
If carnists are truly convinced that carnism is ethical and totally fine for them to endorse, then why do they get so defensive and grasp at straws whenever objective facts about the horrors that they support are pointed out?
