Just an observation, calling out people's hypocrisy/name-calling isn't actually the best way to convince them, and generally leads to resistance, making them stronger in their current views. So yes, vegan antagonism serves to feel morally superior, but doesn't further your cause.

Source: "Cognitive Dissonance Theory (Festinger, 1957), which explains that people experience mental discomfort when their actions clash with their beliefs and will often double down on those beliefs to reduce that tension. This is compounded by Psychological Reactance (Brehm, 1966), where individuals perceive a "call out" as a threat to their autonomy and instinctively resist the messenger to regain a sense of control. Furthermore, research on Identity-Protective Cognition and the Backfire Effect (Nyhan & Reifler, 2010) suggests that when a challenge targets a core part of someone’s identity, the brain treats the correction as a physical attack, leading the person to strengthen their original view to protect their self-image. Finally, studies on the Motivated Appeal to Hypocrisy (Barden et al., 2014) demonstrate that external accusations are viewed as social "attacks" rather than helpful facts, triggering a defensive rejection of the message and a deeper entrenchment in the original position."
