Why are people so rude to vegans ?

I don't know, I've had people be rude to me when they asked what my diet was and I answered. People say vegans never shut up but their limited experiences are online only. They have biases and stuff, have a poor ability to self reflect.

Meat eaters never forget to remind us how much they like steak or make ignorant comments regarding veganism. They never shut up about eating it or offering me it even though they know I'm vegan.

All people lack self reflection, that's all it is.
