There can be no plausible reason to believe objectification is not an issue. It has been shown time and time again how objectification has had a negative effect on confidence, respecting others, rape, the potential to achieve, and overall gender discrimination.
The thing is that sexual attraction is the easiest tool in advertisement to use, because we as humans are sexual beings, and get a dopamine rush when we see something arousing. This is a biological instinct, and therefore objectification of bodies will always be used by advertisers.
I wonder if homophobia is a product of male sexual repression through religious puritanism and/or modern cultural shaming of male sexuality. When was the last time a teenage boy was sent home for his clothes being too tight? There's inherent revulsion among men about putting their bodies on display.
