Superiority Complex?

ShaneMo: that's superficial to me
ShaneMo: to dismiss me b/c i don't have a dick, and i have a (great) pair of tits
fbaddict: yeah it is superficial
fbaddict: *sigh* such a bisexual way of thinking
ShaneMo: yes
fbaddict: but it's true
fbaddict: everyone is bisexual anyway
ShaneMo: what makes you say that?
fbaddict: well, how is it possible to be THAT superficial?
fbaddict: it's like saying
fbaddict: "i dont like thick eyebrows"
fbaddict: same thing as "i dont like pussy"
fbaddict: it could be true
fbaddict: but there are always exceptions
ShaneMo: yeah
fbaddict: but deep down?
ShaneMo: we make fun of our fugly stalkers
fbaddict: haha
fbaddict: but thats different than just having a body part the same as yours
fbaddict: they are just sexually unattractive. millions of years ago, they wouldnt be able to mate. people like them would just die out
fbaddict: shit...whats the word
fbaddict: *thinks back to grade 11 biology*
fbaddict: i know this, im just tired
ShaneMo: natural selection
fbaddict: YES there you go
fbaddict: lol thank you
ShaneMo: haha
ShaneMo: k, i see what you're saying
ShaneMo: well...what if gayness is considered a weakness in evolution?
ShaneMo: if you're gay, it's harder to make a baby
fbaddict: thats true....ive heard a theory that homosexuality was a evolutionary adaptation
fbaddict: i dont know if i was talking to you about that before?
fbaddict: but apparently it was an adaptation to increasing population growths
ShaneMo: hm, no
fbaddict: to keep the pop. under control
ShaneMo: yah, that makes sense
fbaddict: and my theory is just that everyone is bisex. so we have the ability to make the race continue, or not to
ShaneMo: i wish everyone was openly bisexual
fbaddict: which is why prostates only exist in men
fbaddict: (for anal sex)
fbaddict: i know
ShaneMo: ah, interesting
ShaneMo: i kinda look down on ppl who think they're just one sexuality
ShaneMo: i'm like, "you're one-sided"
fbaddict: yeah me too
fbaddict: fucking monosexuals
ShaneMo: lol!!!
fbaddict: they are superficial
ShaneMo: i like this part of the convo
ShaneMo: "we're better than them!"
fbaddict: haha
ShaneMo: i think there are some ppl who truly are 95-100% straight or gay
ShaneMo: i mean...look at richard simmons
fbaddict: hahahaha

I do agree with my friend in part. In my head, I can't understand disregarding love for someone based on what sex they are. But isn't superficiality a part of sexual attraction? What if a certain sex simply isn't sexually attractive to someone?
