Almost two thirds of academics surveyed also thought gender was fluid

Oh, neat. Do gender next.

That is why it is transgender and not transexual. Even then, if you consider sex as "binary", sex is stored as multiple bits encoded as X/Y chromosomes as opposed to 0/1 states and atypical chromosome storage leads to intersex and other anomalies.

Of course it is, you either get sex or you don't.

Seems like a good 30% of conservative dialogue these days is talking about penises. Who cares, get over it.

There are some actual good conservative arguments... stick with those.

The survey is of academics across all disciplines so there is no particularly good reason to treat their views on the topic with particular importance.

There's also this:

58 per cent of respondents think sex is binary, except in rare cases such as intersex individuals

So they're only saying it's mostly binary.

(Censuswide, who ran the survey, as are members of the British Polling Council so we can at least expect them to have run the survey reasonably.)

What are people's opinion of Alfred Kinsey and John Money?
