Why only 'a small proportion of trans folk'? You'd think they'd be out in force, a night all about them, showing up, making a statement, proclaiming their rights, that kind of thing...
Maybe the fact that they were such a small proportion of the audience is because there are such a tiny proportion of the population.
They are so noisy and unreasonable and occasionally violent that it's sometimes easy to forget just how few trans people there are.
