It's rude if the friend has nowhere to go, but there is a huge difference between a friend and your own child and a big difference between giving a stranger your kidney and having your own flesh and blood occupy your uterus briefly, and your uterus isn't cut out and donated.
It is always sad when a person cares about a little so-called right like that over their love ones and babies. But sadly in western culture, people tend to care more about themselves, possessions, sex, fame and fortune, and so-called fun and games and whatever they want more than people, even caring more about it than their own husband or baby. To make matters worse, they don't take responsibility and they look for scape goats to blame. That is seen as both childish and selfish. Seems that people are changing into heartless robots ariound here. Let's see how bad it gets in 20 years, if humanity doesn't destroy itself with its heartless and immoral train of thought. We also see an extreme rise in heartless feminazis who want absolute power.
Plus, just because something is not written in a law doesn't make it right. So if it became legal to kill someone I hate or take something from them, would that be right? Once the path of moral decline starts, it slowly increases until you get something like the Roman empire, then it destroys itself. But bad selfish societies deserve that since they did it to themselves, I suppose. I'll just sit back and watch the show. Who knows the outcome?
But I know arguing it won't do any good, so does this topic have a point since they never go anywhere and no one changes their mind? So I should stop right now. GD threads tend to always end up in fights, and arguments will last forever as long as others think differently.
