As stupid as that person was, the insults with the whole "hippie" and "too stoned" comments are non sense.
First, not all vegans are hippies. In fact, I don't remember the last time the two were in any way related.
Second, not all potheads are idiots just the same as not all potheads/hippies/vegans want to put their animals on a vegan diet.
As someone who has the lyrics to 'Imagine' tattooed, I really don't give a hoot if you call me a hippie. In fact, thank you. But I'm in no way stupid enough to stop feeding my snake rats and mice just because some idiot on yahoo questions thought it would be a smart idea.
Bite your tongue.
