Funny, I have come to the same conclusion about gay people who were ever in the closet. On some level, a practiced deceptive skill has been developed. That conclusion is, in my view, unavoidable. This doesn't mean that the skill has resulted in a person without integrity and basic honesty. And everyone unfortunate enough to ever have to deceive people about themselves on such a fundamental level deserves a shot at proving their ability to productively contribute just like everyone else does, in whatever way their heart draws them.
It's called compassion. It's actually what makes being human worthwhile, if anything does.
