This is what "deep" teenagers post on social media.

Ok so I am atheist, but like literally why should one hate religious people that don't hurt other groups, I think if they want their easy answers they can get them and find salvation from they God or their beliefs.

I mean even though I don't think there is one "christian"-style god, I don't believe in nothing. I believe in science and empirical evidence, which in fact is not objective, because you always have to assume something: Your premises. This is the same in ideology: For whom should the ideology be for? And then why? For example if you try to break down egalitarian movements that believe in equal rights for everyone, you will approach the golden rule: Don't do something that you wouldn't want somebody to be done to you. And this lies on the belief that for every moral situation, there could have been a possibility that the parties are switched and therefore to be moral means to have a set of instructions on which both parties gain equal benefits of that situation.

Then you can ask yourself why did we set this premises, because of course we live in this one universe where the situations are like they are and if I got the knife and we both are hungry I'm sorry but I will kill you (of course if there is no other way).

I see multiple answers and I will present two: The first answer is that in practice this set of moral works. Even the individualism has benefits from an egalitarian society. The last 20.000 years have shown us, that working together is always better than working against each other. Of course this is the ideal world for social darwinists, but you can see that many ideologies benefit from this premises. (But also then you have to ask yourself if your premises should benefit many ideologies or only a handful so this answer is not final)

The other answer is another premise and this is my personal opinion on that matter: I think that ideology and morals should benefit the most people and this is why:

I just think that human life is neat. I mean we did many mistakes but also we did so much good on a cultural level.

And if I really think about it hard: Life is good, even if it means to suffer sometimes and even if it really sucks for somebody or me I am still grateful to have been born and to be able to experience the world and everything there is.

All that you touch, all that you see, all that you feel and ever will be, and all that is now, and all that is gone, and all that's to come and everything under the sun is in tune, but the sun is eclipsed by the moon.

So even if you will suffer, everything will pass and the universe is perfect.
