That's another obvious indication that someone is bisexual. (I'm just making a retrospective point that bisexuals really have no way of knowing, especially earlier in life, that totally straight people never experience any degree of confusion when it comes to gender preference.) When you're totally straight (or totally gay, for that matter), there's absolutely no such thing as any "confusion" because you're exclusively attracted only to one gender and couldn't even imagine being attracted to someone of the other gender. Confusion comes, precisely, from realizing that you're also attracted to some members of the same gender, even (or especially) if you're primarily attracted to the opposite gender. Totally gay people aren't confused about their preference, either, because it's just as natural for them as being exclusively straight is for straight people. (There's often confusion about how they fit into society, what to disclose to whom, and how to deal with being gay or bisexual in a society that often stigmatizes both, but that's not the confusion to which I'm referring.) It's understandable to be confused if you're primarily attracted to women but find certain men sexually attractive, because we tend to think of gender preference as all or none and because someone with those impulses has no way of knowing what it feels like to be completely and exclusively straight (or gay); they only know what their own impulses are and that they have some mixed impulses.
Sorry, but that's not a fair point, at all, and I mean it's not an intellectually fair point. The idea of male-on-male sexuality of any kind is repulsive to me, and I quoted someone earlier to agree that touching another guy sexually is as repulsive to me as eating vomit. I can't watch men kiss in movies without cringing and having all of the exact same reactions as I have watching someone eat shit, or eat a giant live waterbug or squish a cow's eyeball between his teeth, or fuck around sticking needles and shit into bodyparts. There's plenty of shit that gives me the creeps and that I can't watch without cringing. That doesn't mean that I really have some secret or unconscious desire to eat shit or waterbugs; and gay sex is no different in that regard. In my opinion, it's not someone's nonjudgmental and strictly physiological reaction to homosexuality that corresponds to latent homosexuality. In my opinion, to the extent there's any connection, it's the harshness of the pejorative moralizing judgment about homosexuality that's much more likely to correspond to repressed homosexuality.
I'm sorry, but this would be one example of harsh pejorative moralizing that I'm talking about, just like over-the-top focus on anti-gay legislation and rhetoric by legislators who later end up getting caught "taking a wide stance" in mensroom stalls. It's hardly a coincidence that so many vocal opponents of gay rights and prolific preachers against homosexuality turn out to have been participating in various hidden gay activities all along. A person without any of his own issues in the realm of homosexuality rarely has outright animosity to the extent that he has any violent impulses against homosexuals; and the same goes for such an extreme reaction as disowning a child for that reason. Typically, a person who genuinely has none of his own issues in that regard tends to be much more neutral and non-judgmental about other people's sexual preferences.
As a totally straight male, I am very annoyed at any man (apparently) looking at me with sexual interest or talking to me in any kind of "flirtatious" manner, or even holding inappropriately long eye contact, for all the same reasons that women dislike when men do any of those things with no reason to believe that it's invited or reciprocal. I don't like the gay "affect" either, which is how I feel about various other behavioral "affects" that have nothing to do with sexuality. I'm never in any social environments (like gay clubs) where a guy could reasonably think that I might be anything other than straight. But I'm completely neutral about homosexuality otherwise, such as where I have no clue that some guy in the gym is gay until he or someone else mentions it, and I couldn't care less, as long as there's nothing perceivable to me as any kind of interest in me in our interactions.
So, I cannot understand how any parent could have the impulse to disown a child for that reason. I understand not tolerating nonsense like draping giant gay pride flags out my kid's window in my house or being very annoyed watching him loudly advertise his homosexuality and altering his speech pattern to adopt an exaggerated gay "affect"; but I just don't get how (for example) a discrete admission from my a child about being gay could motivate such an extreme reaction from a parent. If you care to answer, exactly what is it about a child's sexual preference that would be so offensive to you, when according to everything we know, sexual preference isn't even remotely a "choice" made by anybody? Obviously, it's a choice whether to act on it or under what circumstances, but I'm referring to the "choice" of being straight, gay, or bisexual. Would you disown a kid who stupidly stole a few cars as a teenager or who got suspended from school for bullying other kids or stealing from other kids' lockers? What is it that's so incredibly offensive to you that you'd disown a son who admitted to you that the reason he never has girlfriends is (let's say) that he's only attracted to males but doesn't want to deal with the stigma of being gay in high school?
