I think that's a horrible analogy.

And yes, there always will, but I think that homosexuality as a taboo has been exploited, specifically.

The analogy is pointing out that homosexuality is not a taboo because it's been exploited, it's being exploited because it's a taboo.

Your original statement seemed to suggest that it is still a taboo because those who wish to exploit it want it that way. The cause is not power brokers, it's everyone (or enough of everyone) who makes taboos' shamefulness persist.

I took issue with comparing psychological/social warfare to physical bullets...

I felt that while both can be weapons, there is a concrete, perhaps subtle difference between the two.

As subtle as concrete
