I think it’s dumb because personally I don’t see the correlation between intelligence and gender. If I’m into tall people does that mean I’m a heightosexual? People need to learn the difference between a sexuality and a preference. Intelligence literally has nothing with gender or sex. Anyone who thinks that, is just dumb.
Intelligence can be “hot”. I certainly find being a dumb-ass to be a turnoff. But I also find it to just be another part of the affection/emotion aspects of orientation.
I break orientation into five categories: Gender (sense of gender, gender expressions can have a lot of impact on how you view things), sexual (of course, your arousal, sexual desires, sexual enjoyment, fetishes, your overall sex drive), romantic (who you can have and maintain romantic passions and romantic bonds towards), emotion (who can you emotionally investment in and who has the ability to break your heart), relationship comfort/commitment (who do you comfortable sleeping next to at night, making a family with, living your everyday life with, going to vacation with, etc). While all those aspects can have preferences, fluidity and/or contradictions depending on the person. And things can also get complicated once you add in money and opportunities and if someone is dealing with mental health issues, issues with deep insecurities, internalized phobias, resentments, hate, religion, a disapproving family, etc. So, yes, shit can get pretty convoluted. And everyone has their own thing going on, their own dimensions, struggles and journeys. Hell, there are dudes are are technically more hetero-leaning sexually, but when it comes to overall orientation they are same-sex leaning.
None of that is to say that many of these people aren’t trying to cultivate personas for sociology, money, appeal and ego. While a lot of people want to be viewed as an enigma or are scared of being seen as “basic”.
