Dear Randip Singh Ji,
Thank you for your response.
The link is to illustrate that some people see Atheism as a dogma today.
Yes, some people may see that. There are also some people that think the earth is flat (there is a Flat Earth Society - I'm not joking). That of course would not suggest that it's really true (those people who believe the earth is flat are simply wrong). Atheism is simply the non-belief or the dis-belief in god. You are an a-leprechaunist right? You simply don't believe in leprechauns, but it would be absurd to suggest that you have a "dogma" that preaches against the existence of leprechauns.
Bottom line is, no matter what, there are good chrisitans and bad christians, good sikhs and bad sikhs, good hindus and bad hindus, good agnostics and bad agnostics, and good atheists and bad atheists. I will be the first to admit that, and I will be the first to admit that I have done wrong things in my life (would anyone else like to conclude anything different about themselves?). I would argue that the thing that defines one's character is what they do and what they learn from the bad mistakes they've made. Making mistakes is simply human.
Anyone who is atheist that acts poorly or attempts to act in a dogmatic way is also wrong...but atheism doesn't teach that...atheism doesn't "teach" anything, just like a-leprechaunism doesn't "teach" anything - they are both disbeliefs in a fictitious character. So by itself (in and of itself), atheism is not a dogma. Those who treat it like one, atheist or not, are wrong. Similarly, by itself a-leprechaunism is not a dogma. Those who are foolish enough to use it as a dogma need to see my friend (who is training to be a psychiatrist).
1) Atheism is based in rationality? Yes
Agreed (just like a-leprechaunism)
2) Religion is based in belief? Yes
Agreed, although this is not exactly an argument in its favor (the Flat Earth Society is based in belief too).
Belief cannot be explained through rationality, so never the twain shall meet.
Again, not an argument in favor of "belief" since after all the Flat Earth Society is based on belief, and it would be absurd to simply say "well the Flat Earth Society is based on belief, so no matter how much rational proof you provide that the earth is round, you can't challenge my 'belief' that it is indeed flat."
What we have nowadays is Atheists trying to tell religious people that belief is not rational......well duhh? 
Yes, we do have atheists saying that. Believing in leprechauns is also not rational. It is fine to admit that it is from "The Journal of Duh" and I'm actually pleased you did. Lots of christians tell me that their religion is completely rational (I particularly like how they say people used to live 800-900 years but now we live less because we are sinners - as if people did not sin back then...and since the life expectancy is getting longer and longer, does that mean we are now sinning less and less but not quite as less as in biblical times?).
Religion is non-rational but that's the not the big issue. The Flat Earth Society is non-rational but 99.9999% of everyone could care less about it, right? It doesn't bother you and you don't lose sleep over it right? If you do, see my friend.
What we're trying to say is that not only is religion non-rational, it can be
dangerous. For example, in the US there is a christian dentist in Texas who seems to have a lot of influence over what is written in textbooks that elementary school children read. Because of his religion, he would like nothing more than to have his creationist fairy tails in those textbooks to indoctrinate children from an early age. So his non-rational belief is seriously becoming dangerous. If he were to succeed, I would have to send my kids to a private school.
Let us not forget suicide bombers, the crusades, & the Aztecs who ritualistically (per their religion) cut out the heart of someone and while it was still beating threw it down a long stair case in some ****** egregious practice to please their god. So it goes beyond non-rational...religion becomes dangerous.
Of course, I will admit that Sikhism is light-years ahead of other religions. If it were a race toward the truth, and all religions were contestants, it wouldn't even be a close match. That's how rational Sikhism is compared to other religions.
The concept of caste is out-dated and, while some may hypothetically say that "back then" it had a role, it has absolutely no role today. People worrying about it, arguing in families over it (ie marrying out of caste), and even caring about it are wasting their time. I could care less what "caste" I am and in this day in age it's unbelievable to know that I have been rejected by girls because I wasn't a jatt.
I hereby remove my caste, I am now a neutral human being without caste.
