What
Dorian and
DevilEyes indicated (whether seriously, jokingly or just as hyperbole) is that Deborah is so attractive that if they changed their sexual orientation, they would go for her. They're talking about level of sexual attractiveness That means having sex with her. What their, or anyone's, pre-sex protocols are are irrelevant to that because it's entirely hypothetical. It's just an issue of how that concept is expressed in polite company. And what is acceptable in polite company is fluid and changes according to time and place. Many discussions and turns of phrase that are acceptable here and now would not have been acceptable fifty or a hundred years ago.
And, for the sake of perspective, it's also worth noting that the very idea of changing sexual orientation is still offensive to many people, including people on this BBS. And it would be used as fuel for their ideological belief that sexual orientation is a choice. You can politicize, or be offended by, anything if you're determined enough.
The bottom line is that
Dorian and
DevilEyes, like most of the rest of us here, were just expressing their opinion of Deborah's beauty and sexuality in an amusing way. They didn't feel the need to say that they would bring her flowers, take her out to dinner, wait for the standard third date, proposition her and then gracefully bow out if declined. Nobody should have to consult their lawyers for the proper disclamatory language before posting. Women talk about men, men talk about women, women talk about women, men talk about men-- that's not sexism (or homosexism) or objectification. It's sexuality. It's fun.
If any individual is impolite or insulting, then that individual is dealt with. Other than that, it's just fun.
