Believing this will make you hate yourself, and others, enough even to kill yourself, or other people like yourself. Many, many transsexual and homosexual people are killed, and have been killed, by this belief. Truth cannot be pointed at, touched, or put in a jar. Truth is a concept, not an actual thing. Truth can be based on emotions, as in 'Emotional Truth', or even on best guesses.
All truth is is an emotional measure of the veracity of information.
Truth does not even automatically imply facts. This is problematic for several reasons. All facts can be questioned, and must be capable of being proved to remain facts. There can be no such thing as an unquestionable fact. Absolute truth exists to silence any debate, to quell any curiosity, to censor any opposition.
