Here's the thing about "If you don't have anything nice to say, don't say anything at all."
It doesn't apply to public figures. If people who don't have anything nice to say about a politician, they can and should criticize said politician. If a celebrity makes an insensitive remark, you can bet your bottom dollar that they will be called out on it.
And if a public blogger sets a horrible, dangerous example, they should have to face criticism for that as well.
You want to know why I disappeared off the face of the blogworld for a while?
YES I was focusing on other things.
YES I was very busy.
But what's the real reason?
I was (and still am, to a certain extent) so goddamn sick of the bullshit.
The health/fitness blog world seems especially afflicted by Obsessive Compulsive Bullshitting Disorder.
If you look like you weigh about 95 pounds and go on and on about having a healthy approach to food and exercise while eating grilled chicken and "unpictured ice cream and chocolate!!!" and taking pictures of your biceps that only look huge because there is not one ounce of fat on them, please shut up, stop blogging, get your shit together, and stop being a bad influence on other women and young girls. Blog your struggle! It's a very valuable story!! Blog about something else! Just don't normalize horribly disordered eating habits and thought processes. Don't. Do. It.
Likewise, if you look like you weigh a very frail 90 pounds and subsist on an impeccably "clean" diet and have to wrestle with the thought of a cheat meal, and have never posted a video of yourself squatting so much as 45 pounds, do not try to tell us that you squatted 185x6, which would give you a one-rep max of 215, which is greater than a record for the 97lb, 105lb, 114lb, AND 123lb women's raw powerlifting divisions per the USAPL. Are you kidding me? Do you know how long it takes for a female to work up to a 2+x bodyweight squat? By claiming to have so easily achieved this goal, you cheapen it for those of us who have busted ass, eaten our butts off (well, on, really), and trained for YEARS, to reach that goal.
You are also creating a very DANGEROUS atmosphere for aspiring female bodybuilders and competitors. Those types of women tend to be very competitive, and for them to see someone who has been training for two years and eating almost nothing (and certainly nothing indulgent) allegedly hit a goal like that, you are endorsing the type of starvation diets that are rife in this part of the fitness world.
You know who you are, and if you post a clear video of yourself squatting that weight (I mean, really, you did that and you didn't take a video to commemorate it? When you take 4958736 pictures of yourself flexing every day? Give me a break), I will eat my hat on a live feed at justin.tv. Swear to God. You read it here first.
Blog responsibly (at least try; I know no one is perfect) or don't blog at all.
