Not that jeff is doing this, but I'd probably be more disposed towards vegans if they didn't get so militant about preaching their lifestyle. The ones I have met personally -- and I know who they are because they proclaim it loudly (whether you asked or not), tend to ride everyone around them about their diet choices.

Its pretty goddamn obnoxious.

I like how Jeff goes about it though, he just puts it out there and you decide for yourself. Which is what I wish most of the vegans would do.
