The Luxuries We Can Now Afford
To dilute somewhat the normal amount of chemical warfare I bring to this issue, I will try to speak more humbly on the matter.
This involves setting aside religion entirely.
There used to be contexts of history within which the argument COULD be made that homosexuality is a luxury that a desperate, offspring-starving population could not condone. There were too many crops to harvest by too few hands. Women needed to get to baby-making tout suite, and I guess the silverback of the village got to decide which males besides him baby-made.
Those days are over. We can afford the luxury of living with homosexuality between consenting adults.
Another luxury we can afford? The concept of consenting adults.
Another? Making love. Of course, any two people can have who cares sex, turning themselves into circles on a Venn diagram intersecting at the crotch. It takes something (dare I use the word) magical to truly make love.
Also, the age of 18 meaning anything in our society, allowing people to live together whether they're called spouses or not, and minding your own business.
The problem with the word sexuality is that it encourages the emphasis on the sex itself, when homosexuality is every bit about butterflies, first dates, stupid fights, and "to love another person is to see the face of God" as anyone else's humble attempt at a love life.
