It was an effective way to avoid being called out as a privileged cis-het-white. I think this is part of why identifying as trans or ‘neurodivergent’ also became more common.
I working on that right now but the first hurdle of replicating these results is quite difficult. Whether weighted or unweighted, nothing I get seems to match. Regardless, looking at unweighted ¬Heterosexual, it shows the same shape as Figure 1 so that should be a partial answer to your question.

You said that the "other" category is excluded. Has that category been increasing over time?
In other words, are bisexuals converting to straight? Or are they converting to "pansexual", "demisexual" and other exotic things?
