"Using the troubled logic above male masturbation would be equivalent to genocide."
Not true. A sperm without an ovum is not a human life.
What a ridiculous statement of course masturbation isn't genocide but it's wrong because it defeats the purpose of what semen was made for not that every seed is going to make a baby as God determines this- no one ever said it was genocide, but all Protestant denominations taught that masturbation was wrong and that contraception was wrong up until the Anglican Lambeth Council in 1930 I think. That was the same denomination which now teaches that homosexuality is OK and homosexual marriage and ministers are OK as well. That was the same denomination whoes founder murdered 5 or 6 of his wives because they could not produce him a male heir to the thrown. Read Gen 38: 9-10 and Gn 1: 27-28 for what is a blessing and what is a curse.
If you are more of an atheist here is a quote for you
4.Freud writes, 'Moreover it is a characteristic common to all the perversions that in them reproduction as an aim is put aside, this is actually the criterion by which we judge whether a sexual activity is perverse, if it departs from reproduction in its aims, and pursues the attainment of gratification independently. You will understand therefore that the gulf and turning point in the development in the sexual life lies at the point of its subordination to the purposes of reproduction. Everything that occurs before this conversion takes place and everything which refuses to it, that is to the purposes of reproduction and serves the pursuit of gratification alone is called by the unhonored title of perversion, and as such is despised, taken from The quotation area from a series of lectures given by Freud in Vienna during the school year 1917-1918 Freud General Introduction to Psychoanalysis, published by Liverwright publishing Company in 1935. page 277.' see Natural Law and Birth Control by Scott Hahn
