Those who claim that homosexuality is right, their reasoning is that these people should have the freedom to have a relationship which they desire without anyone restricting their rights.
They also believe that the homosexual gene can be inherited [although i wonder how this is if a homosexual couple cannot have children together.] Although there is some research to support this, there is also research to prove that homosexuality is not genetic and effected by society only.
Incest Moral?
Now, if people use that as the basis of argument - then they need to question whether it is okay for a brother and sister to commit incest? If they love each other? Why is it still illegal in many parts of the US whereas homosexuality isn't?
If they still agree with that, then they should know that this is immoral, not just because they are having sex with their own family members, but because their children are likely to be affected a great deal by this, since having sex within closer relatives poses more of a threat of genetic diseases.
Sex with Parents Moral?
If the person still believes that they should be allowed to do that, then is it also moral to have sex with ones mother or father? If they both are mature and fit for it, willing to do it?
If someone says that this is moral, then who will their children be? Will they be sons/daughters? What will their child be to them? It can't be a son/daughter, nor can it be a brother/sister - so who is this child to them?
Is this really moral?
Sex with Animals Moral?
How about having sex with an animal, is this moral? Some may argue that animals cannot consent for sex, but what if an animal makes the first move and approaches the person sexually, is it moral then to have sex with that animal?
Eating your Partner?
If the person is still going to play along and think that this is moral, is it moral to have sex with ones partner, and after having intercourse with them - you kill them and then eat them. Is this moral, if both parties had consented to it?
Since people like comparing themselves to animals so much (by arguing that some animals do homosexual acts 'so humans can do it to'), i'd love to hear a response to this - especially the last one (since
fishing spiders * eat their mates after mating.)
VORACIOUS female spiders just cannot help trying to eat suitors before sex. Why? It's their aggressive personalities.
Females of several spider and mantis species dine on their partners, but only after acquiring the sperm necessary to fertilise their eggs. By providing his mate with a good meal, the male increases his own reproductive success. But that doesn't explain the behaviour of females that opt for dinner instead of sex, as fishing spiders (Dolomedes triton) often do. "Eating your mate during or after copulating, that's no big deal. Eating your mate beforehand, that's weird," says Chadwick Johnson at the University of Toronto, Canada.
