No one is "hating" the concept of elderly bodybuilders. The majority of elderly bodybuilders you have posted do not look well. A few looked fine.
If someone is repulsive looking, people do not want to see them in posing trunks. Many of the geriatrics that you have posted look horrendous. If an artist went into the toilet stalls of Grand Central Station in NYC and collected all the unflushed feces...and then mushed all the feces together to form a sculpture of Gonzo...and then put that on display as an exhibit at the Metropolitan Museum of Art...and people thought it looked vile...that wouldn't be hating. The same goes for these elderly folk.
And any progress or chance that the elderly bodybuilding movement had to succeed and become more popular/accepted has been decimated and damaged by you and your posts.
