Bisexuals have more choice than others. They experience attraction to the same-sex, but also to the opposite sex.
Say you have this hypothetical bisexual who is pretending to be straight. He doesn’t want to pursue men for a number reasons. First is the church, but there’s also the fact that homosexuality is frowned upon in mainstream society. He doesn’t the discrimination and negative attention homosexuals receive, and bisexuals usually don’t get much better treatment. So, as far as anybody else knows, he’s straight.
However, there is still some desire deep inside of him, whether he feeds it or not. Others eventually notice his ‘otherness’ and confront him about it. He has nothing to gain by coming out, since he has no intention to pursue men.
In this scenario, would lying be morally acceptable? Even dancing around the issue would blow his cover, since any legitimately straight man wouldn’t have any issue answering the question, and would answer swiftly.
If lying is unacceptable, what would you advise this hypothetical man to do? He doesn’t want the discimination that homosexuals receive, and he doesn’t want that kind of reputation, especially since he hasn’t, nor will he, do anything to earn that kind of reputation.
