Probably because a lot of this community has an uncanny ability to be condescending and judgmental. I don't care if someone doesn't eat grains or sugar, I care if someone calls me an unhealthy piece of shit for drinking a coke and proceeding to go into a tirade basically looking like an insecure stressed out nut.
To those who don't discuss diet, good job. To those who wig the fuck out for no reason about it, bad job. If some other guy throws the first insult, it's free game, but my advice: it's not worth arguing about.
Unless you're bored online of course.
where am I to find a voice that's pure and urging me to climb?
