But neither do I condone the present in-your-face propaganda of something, which is - again - a private matter of the people concerned. Just like in the 50's, so now this should remain within the privacy of the people's bedrooms.
They used to say the same about interracial relationships, until we realized that was awful bigotry. These types of relationships were were illegal in the USA until 1967's Supreme Court Loving vs. Virginia.
Both heteros and gays alike should be able to fuck outside in public parks, in full view of your children. Sex causes no harm to anyone, it only offends theists, and they need to shut the fuck up about what offends them because NOBODY CARES, NOT EVEN YOUR GOD OR YOUR DOG CARES.
It's a figure of speech, that you took literally. I meant that it's their private matter, not to be imposed onto others. Oh and heteros copulating in a public park is a bad thing as well. I am not interested in seeing how others do it, and so see no reason why others would want to display their horizontal dances to the general public.
The question of LGBT is pretty simple. But just like with any topic, where a powerful group pushes through it's agenda, this too is muddied and made to look more complicated.
Let's look at it from logical and biological perspective, setting aside emotions.
Let's start with the following premise. In the vast majority of cases, a man is sexually attracted and aroused by a woman, and a woman is attracted to and aroused by a man. This has a clear biological function of procreation, of getting healthy descendants. Any pleasure derived from the act is a boichemical form or reward (with a substance related to morphine) for an energy-consuming act. Any felling of attraction when being with someone of the opposite sex is there to ensure that the couple stay long enough together to raise their descendants, providing them with enough energy and life-knowledge.
What about the case when a man is attracted to a man or a woman is attracted to a woman? Biologically it's a dead-end with a built-in self-destruct mechanism. No descendants are coming after such specimens. And whatever permutations in their gene compositions that lead to cause such behaviour are removed from the gene pool.
What about cases, when a man or a woman are sexually attracted to a child? Not much different from the above, really, when it comes to basic biochemistry. Some groups in, e.g. Holland are working on legalising paedophily, which would expand LGBT into LGBTP. The biggest difference is that a child, who most probably has no deviation from the norm, gets forced onto itself a certain behaviour damaging/reprogramming said child.
For the same reason, adoption of children by LGBT is damaging for the child involved. Even if it's not violated physically, it's worldview, which is in the stage of fragile construction, is violated psychologically.
