I honestly wish someone would have been and rude to me before I started this whole thing. It would saved me so much pain and turmoil. If someone would have be brave enough to offend me and tell me to go away... I wouldn't be where I am today.
So you really think, without taking in to account how you now know you feel about it now that if someone had been rude to you that you would have then just thought.
"Oh, yeah that was mean/rude and made me feel bad/sad, I should probably just stop trying to lose weight and pick up nitting, that seems like a good hobby but none of this nonsense for me" ???
My guess it that reaction is rare if even it exists, more they just feel rejected and even worse and when someone feels like that it always ends up fine right? Just push people away and they will learn that they are wrong and you are right?
Also what you might feel and think doesn't change the fact that this site has a purpose other than your agenda, people come here for all reasons, newcomers might also have difficulty talking about how they really feel, making it seem light and funny is a way of coping for many so what you see as brave might not be for others. If being a jerk, being rude or judgmental is the same as being brave in your book then... I'm at a loss for words, really.
And also with that attitude why don't you just stop being like you are, if you're not happy, why are you here? If someone questions your motives or reasons, belittles you and so on, you just think "oh, what a brave person" ??
