Why does the human race still demand that you have kids?...
I didn't read the entire thread, but to answer that question: It doesn't demand anything, We are still animals and on the most basic level we are created to procreate.
Do we have to ? No we don't at all. It personal choice because we have a certain level of intelligence that allows us to make responsible decisions. Obviously, not all humans exercise that decision and have kids when they shouldn't and some people who don't want kids might actually be great parents and never get that life experience.
Some of you who do not want kids based on your 'personal freedom' to travel and do things you like to do that is cool. I happen to think you are being responsible people for not having children as the sentiment expressed is that it would take away from your own life because that is what you want to concentrate on. Perhaps, you aren't ready to put your own life aside for your own child so its a good thing that you don't because it might make you miserable and be a bad parent.
My wife and I just had our first child and I can say that I really couldn't be happier in life, it's so exciting and different. She is 2.5 months now and so much fun. To think I would actually have a child compared to me 5-10 yeas ago I would say it would never happen, but life changes. It's so weird to me sometimes. We have this little human that doesn't know anything about this world, can't walk, can't talk, has limited vision and I get to witness her grow and learn all of these things. It's pretty cool.
Having a child changes your perspective of life. You don't think about yourselves first anymore, which is something I welcomed with open arms. It's not really a big deal, you find time for you and your significant other to have time for yourselves to go for drinks, movies, concerts, whatever. I already had my selfish fun, traveling, partying, promiscuous behavior and I just came to a time where I was just done with it. I met the girl I love and having a kid does not take away from any hobby or interest I have, and it gives me a new one. I realized that it's a progression in life, my life, that is.
People are just looking at western society, which basically is on the decline as far as population is concerned. Look at polygamy. Muslims are out-reproducing Europeans, by something like a 3 to 1 ratio and it's impossible for them to catch up. In a few decades Europe will be dominated by Muslims.
