I wonder how many lives they need to ruin, how many laws they need to pass, and how much cultural damage they need to do before they realize, that it's not working. How long before they realize that the nagging anxiety, mental discomfort and shame and guilt that drives them is not being caused by everyone else? How long before they realize that their problems and suffering are coming from within?
I doubt that such a realization would help much because if you examine homosexuals, you find that a much higher percentage of them than the population as a whole have *other* problems.
Not just mental, but physical as well. Often they mask such problems by assuming they have a sexual origin, when that is far from the case.
Unfortunately, they are strongly averse to having a study done to find out what else they should become aware of as common problems. And in truth, there are those that would use such information to assert that homosexuals are defectives.
It does point out what you said, however, that projecting personal problems onto others is ineffective in finding remedies to those problems. But projection seems to afflict a LOT of people.
