all the "vegans" I have had interactions with online were absurd, emotional, and mentally deficient.

Emotional, yes. Empathy tends to do that.

Absurd? Mentally deficient? Be more specific. I suspect you don't like being confronted with the consequences of your choices, so you deflect instead of reflect.

they can't be real because nobody would be stupid enough to weaken themselves by strictly eating vegetation.

Weaken? Apart from B-12, which many people take supplements for, what do you think is missing from a vegan diet? Certainly not protein; beans are wonderful.

besides wouldn't hurting people go against their whole "vegan" moral superiority?

Not necessarily. If a person is causing harm and refuses to stop, they may have to be physically stopped.

I'm saving this, thank you.
