There was a time when the LG denied the existence of the B (iirc brain scans have shown differences disproving this).
Possibly at a similar time, there were pinks who denied that *anyone* was 100% straight, to which I claim in that case no-one is 100% homo either.
Is it possible that people differ in their T-dar, so there is no definitive labelling of a particular coupling as gay or straight ?

Headlines are designed to be click-bait, so we should expect them to use unexpected definitions to provoke.
