Is It Still Okay To Make Fun Of People At The Gym?

I'm not joking when I ask if it's still okay to make fun of people at the gym. And I don't need to turn this into some longwinded expose on gym etiquette. I'm simply curious how we've gotten this far in society to let some guy moan and groan and parkour across the free weight section without any intervention. And to that, I don't know if it's safe for me to even ask the question. I can see all the pussies lining up right now supporting this guy for Trying Your Best!

....in business casual?

Excuse me. It's been a while since I've bullied someone at the local X sport. All I know is that if you tried to pull this shit in my day at the University of Illinois or some other similar public university's rec center, there'd be a Pike telling you to shut the fuck up within 2 minutes. And I mean directly to your face. Some 6'3 glazed and bronzed senior named Brad would come up and ask if he could mix in reps. Then he'd take all the weights off your bar and tell you to come back at 9pm when No one's here for you to fucking bother. Have I seen that happen before? You tell me. 

Elsewhere, I think the evolution of us taking our criticisms to social media broadly has severely impacted our collective ability to shame people out of behavior patterns. The shit talking is no longer a 1-to-1 transaction which also means it's a diminishing skillset. Confronting someone in the flesh will be a lost art. Telling someone to fuck off will gradually become less common place and I think we all agree that's not good. 

But for now, I need to know if we can make fun of this guy. Or does calling out objectively unreasonable public behavior make me a bully? Hard for me to keep track these days so I'll leave it to you guys.
