I would agree 100%...it was watching guys like Mike O'hearn that inspired me to lose and weight and start hitting the gym after watching his youtube workout videos & fitness info.
Unfortunately, society seems to be moving more toward the mindset of insulating people (who aren't taking care of themselves) from criticism.
All of this "you can't fat shame people" stuff is bogus in 99.9% of cases. I get that in very very few cases there could be a glandular issue or something that cause the person's weight to skyrocket out of their control...but like I said before, that's a fraction of a fraction of a fraction of the people that are overweight.
The vast majority of people that are overweight are in that situation for one (or many) of these reasons:
1) Doesn't have the will power to limit junk food intake
2) Doesn't have the self-control to not over-eat
3) Doesn't have the will power to exercise instead of sitting on the couch
Even with just reasonable portion control, and reasonable limits on caloric & carbohydrate intake, and a modest four 20 minute workouts per week, a person could stay reasonably fit healthy...you're not going to get "jacked" or "shredded" with that, but they'll be reasonably fit.
People who are fit, shouldn't have to walk on eggshells...and people who are making poor choices shouldn't be immune from criticism from people who are fit.
We wouldn't do that with any other form of poor life choices...
For example, if I saw someone running with scissors, and said "are you some sort of idiot?!?! stop doing that!!", the PC crowd wouldn't rally around that person and insulate them and say "that's scissor shaming, and you can't do that! it's not nice!"
Our society is slowly turning into a Harrison Bergeron scenario (for any Kurt Vonnegut fans in the audience lol)
