From the logic of these guys if lesbians fetishized bras, will it now make any women a lesbian to wear a bra?
Logic has nothing to do with it.
The gay community has embraced jock straps as fetish wear - of this there is no doubt. You don't see male performers wearing jock straps in straight porn.
The jock strap has been replaced by compression shorts in every professional sport. I suspect those guys know what they are doing.
