On the one hand it's liberal in that it has you consider and reject things other than the the normal tried and true way of 3 meals a day, 7 days a week horseshit society feeds you. On the other hand it is very conservative because a life of strict schedules/diet, hard work and consistency is conservative in nature.
A conservative, is almost like proving a negative in that they want LESS government, where a liberal wants more.
So in terms of bodybuilding, a liberal would want a stronger presence of the IFBB, all sorts of mandates, more rules, and of course more money going to IFBB board members.
They would create all sorts of positions like IFBB certified health experts, a board of doctors that clear athletes to compete and demand you buy health insurance through an IFBB affiliated medical insurer. IFBB guru certification. To "protect and care" for the athletes. They would have a supplement "board" that would decide what supplements would be IFBB certified, with a matching price tag. They would censor all talk of steroids, citing how kids could get the info. There would be rules that no bodybuilder could ever talk about steroids or PED's or face being banned by IFBB.
Over time, the rules would becomes stricter and stricter, and the IFBB more and more powerful with mandates, This would all be done in the name of "protecting" the bodybuilding community. Then of course taxes AND fees. It would cost a FORTUNE to hold an IFBB certified event, because of the taxes and fees, as well as fines for all sorts of violations of IFBB rules, which would become more numerous each year. Pro cards would cost MUCH more, to pay for all the new IFBB board salaries. The power that these liberals would have over bodybuilding would breed corruption including biased decisions, financial fraud, and sexual abuse of competitors both male and female, who would be afraid to come forward because of the IFBB's power over the sport.
A conservative would say you're all free to pursue bodybuilding how you see fit as an individual. The IFBB is here just to evaluate your physique onstage.
