why people can't just eat and shut the fuck up

I can understand their reasoning behind this. Most people won't get it as they think of veganism as a diet or lifestyle preference like the non-vegetarian diet. But according to those vegans, they look at it more as a social justice movement than a personal choice. Animals shouldn't be treated as some object or a commodity as they are conscious individuals who are defenceless victims of cruel humans. More so, when this cruelty can be easily replaced by compassion by consciously adopting new diet and habits. The relatable examples offered is of cases of rapes, domestic violence or child harassments. If you would like to defend and rescue victims of these violence and won't shrug it off as it being their personal matter; you ought to behave similarly for innocent animals being victimized too. Ofc, I agree that screaming and calling out as murderers is a bit insensitive of them but this is prolly an outcome of their emotions when they feel helpless to rescue the innocent victims.
