I didn't think of that angle, and I think you're RIGHT.
That's why homos didn't used to be able to get security clearances.
Yup, exactly. History is filled with examples. Most people never stop to think about where the old phrase “Caught with a dead girl or a live boy” came from. It came from Politicians being caught with dead girls and live (IE Homosexual) ‘boys’.
The incentive for a closeted or even open homosexual to give in to blackmail is myriad. Thats why Sec clearances were only given to the most ‘stable’ and upstanding - once upon a time. One practically had to out-straight and narrow the Pope to get one. Today, they are seemingly given for the opposite - and so you get compromised/compromisable people in positions they ought not be in.
By design.
