Atheists defending morals (humanity, rights, freedom, justice, etc...) is one of the most absurd things ever, are you guys aware of the consequence of your beliefs? do you know what is it like to be a real atheist?
Consequences of our beliefs? No religion has yet been able to substantiate their religious assertions with empirical evidence, they have been given thousands of years to do so...
But there is evidence of things like the Big Bang, Evolution, Homosexuals and so on. - They have been substantiated.
From an atheistic view, we are just a bunch of atoms without purpose and meaning (nihilism), good and evil are illusions, and the belief that a certain act is good or evil is an arbitrary conclusion, "It's pretty hard to defend absolute morals on grounds other than religious ones", Richard Dawkins says.
Absolutely false. Good and Evil does exist, but they can differ from ones own perspective.
Morals are a human construct... Morals are built from things like empathy and pain. - In short, we share empathy with someone who is in pain... And would not like to experience a similar pain or inflict that pain upon others.
And we can always talk about the Terrorists who leverage religion for their heinous crimes and the amount of Christian leaders who have been unjust towards children... Where the hell are their morals?
In short... Religion is not required to have morals, I save peoples lives daily, I am a hard-line atheist, unless you are suggesting I don't have morals?
An atheist who's honest with himself wouldn't care about others lives, as long as he's not concerned. he won't let "moral values" prevent him from pursuing pleasure in his finite life (hedonism), why would he not kill if it won't have negative consequences on him (aka punishment, which wouldn't exist in a purely atheistic world, only the law of nature do).
Pleasure doesn't override morals.
And an Atheist would and can care about himself and others, again... Empathy.
You can blame your consciousness for that, or keep lying to yourself. As for the homosexuality topic, I recommend reading "My genes made me do it!".
Homosexuality has already been scientifically established that there is a biological, environmental and social aspect to it.
In saying that... Homosexuality most certainly does come into conflict with the main 3 middle eastern religions, Christianity, Islam and Judaism... But again, after thousands of years, millions of followers... None of those religions have been able to establish their various assertions with empirical evidence... And thus Homosexuality should take priority in matters.
You totally missed the point.
You said it yourself, "good and evil does exist, but they can differ from ones own perspective.", so what if I see good in killing? why does that bother you if you're not the one being killed? it's my own perspective of good, you might say humanity and compassion and whatnot, I say that they're relative too, why would you want to impose your standards on me?
Most of the "prophets" of atheism like Richard Dawkins, Lauren Krauss, Carl Sagan and Sam Harris, all see that morals and ethics are relative, so defending them rationally, without falling into logical fallacies and rhetoric is a waste of time, you just have to read. also, being a human construct doesn't mean it's the right thing, relativity of morals destroys the concept of right and wrong.
You save peoples lives, and? what do you gain from that? only feeling good about yourself because you believe in the illusion (from an atheistic view) called absolute morals, and either if you save lives or kill people your destiny is the same: void, sooner or later. there's no point in risking your own and only life to save others lives, this is absurd.
The arguments against religion that you presented are overused by superficial atheists, besides relying on the absoluteness of morals (which can only be true when there's a superior authority that defines what's right and what's wrong and rewards the right doers and punished the wrong doers), there's more to say: the genetic argument was debunked long ago, you just have to search, homosexuality is nothing but a normal consequence of the sexualisation and pussification of the western society (no offense), including teaching children that those kind of sex topics are banal.
As for the terrorism argument: are the evil acts of a certain group that claims to follow an ideology an argument against the ideology itself? obviously no, read about Islamic rules of war and true jihads, you'll find that killing women, children, old people, priests, craftsmen, captives, unarmed people etc... is prohibited, only adult armed men who are engaged in the conflict can be fought. of course you don't know that because your source of info is working on tarnishing the image of Islam, what did you expect from them? and still this is just a tiny portion of the truth.
You're dealing with Islam here, not Christianity, the big bang theory is clearly stated in the Quran, as for evolution, there are muslims who believe in it, those who believe in guided evolution and those who reject it, if you want me to open that topic too I'll gladly do.
I had doubt about my religion for a long time, if I didn't properly learn about atheism I wouldn't have given Islam a second chance. I invite you to read more about atheism, and Islam from muslim sources, rather than being content with what you've been told and persuaded with by media and school.
