That person is an outlier and should not be considered for personal comparison.
A spectrum has more than two parts. Think of a political spider.
I'd always visualised sexuality as at least a triangle of straight/gay/ace, and everyone would be a point inside the triangle? Just a "straight line" seems too simple.
No doubt someone can suggest another axes to make it the sexuality three-sided pyramid, but not more than that, please; too early in the morning to try and visualise a hyperpyramid.
Even that is an oversimplification. For example bi people who only like cis people.
People are just into random sexy stuff and we lump them into groups.
All I know is I wanna fuck Sandy Loam whoever they are.
What about a gay line?
I've maybe explained it a bit badly - I was thinking "like the soil triangle", but for sexuality. So you'd have the "100% gay corner" rather than "100% sandy".

edit: oh, yeah. A "straight line" between 100% straight and 100% gay would be too simple, in that there should be more options. Should have used a different term, but what I mean is that you can't just assign people a single number here, people are more complex than that.
Nonono, it was a joke: straight line, gay line... eh? 🤷♂️
it was a silly game of words
It's me. I'm the gayest. :3
Called it! I'm just waiting to collect my winnings. I'd like to thank all the people who believed in me, and the gods (of course) for making this possible.
That is a rather impressive amount of gayness.
Totally ;)
Could be an open set, with a Cauchy sequence of gayer and gayer folks, but not including the limit point.
We've got a finite set here, so that would imply there is a gayest person at any given moment of time. But yeah, I would expect it to have multiple variables and not guarantee existence of the gayest for all parameters, the chosen one if you will
I’ve only met a finite number of gay folks, but I’m willing to accept the possibility that there are infinitely many gay folks I haven’t met!
Someone had to set the bar.
The gay bar?
Digbar?
Going to hell...?
I'm going to Hell for this
