So to be converted to a religion (Islam only being an example here) it would have to provide a better moral and positive emotional framework than Christianity?
Side-note: This is separate to the question above, but on the topic of the post you provided on positive thinking, I think it may have something to do with religion being less common in a trend among those who are both wealthy and in a higher quality of education (i.e. tertiary education has a lower instance of religion than secondary, public has a lower instance of religion than private, CEOs are less religious than white collar workers, etc) along with a number of other factors that I can't recall, and that these factors do increase tendency towards negative thinking. There is a truth in the stated Christian doctrine (as is shared in Buddhism, Taoism, Hinduism and others) that material goods do not bring happiness or 'salvation'. I personally do not believe, however, that this makes those who are atheists less valid in their beliefs (I would hope so, being an atheist myself).
I would disagree with you completely on this. You are outright dismissing a point of view with no supporting evidence other than a vague, insulting comment. It appears you haven't actually learned what this site is promoting. It's one thing to disagree with Yaro here, it's another to outright insult his beliefs and simply raise his barriers in agreeing with anything you believe.
I've seen similar instances occur enough times to know (within a reasonable margin of doubt) that if you want to actually make a person agree with you, you start by making yourself agreeable.
