To my understanding at least one religion promotes peace through unified belief (more or less) where the only way the religion is peaceful and loving is if you're a part of the religion. If you believe something different, you're a heretic and must die, for peace.

IDK, killing people in the name of peace seems counterintuitive. There are times that you need to kill warmongers to promote peace, but killing them for peace because their sky friend is different than your sky friend seems like it's a bad philosophy.

I've been aware of this for a while and I have yet to be told I'm wrong, or have anyone provide evidence that I don't understand what it says. I have, however had people verify the concept to me several times. I'm always on edge around people of that religion because if they're being told that people from other religions, and people who won't accept their sky friend as the one true sky friend, should be killed. I'm almost never sure if they're going to try to kill someone to progress their religion by removing heretics. I just can't relax while people from that religion are present because of this. Unless I know them pretty well and know that they reject that philosophy.

Due to this, I'm kind of opposed to "religion is fine as long as it's believers are peaceful" and I'm more in favor of the concept that all religions should be disbanded as a relic of an era where we couldn't comprehend a lot of things that science has since explained away.

I don't subscribe to any religion because they can't all be correct, if any are, and because there's no differentiating information that lends any scientific validity to any one religion, and in the absence of a "God" giving some kind of indicator as to which one is correct, I'm forced to assume that with the plethora of conflicting ideologies, that none of them are correct. I have to believe that if there is a God who wants you to believe and obey one specific set of beliefs, that (s)he would make some kind of effort to clarify which one is correct; this leads me to think that either God doesn't exist, or doesn't care. Given that, I just try not to be a "bad person" and live a moral life, and if I die and find out there is a God, and (s)he wants humanity to believe a certain set of gospel, then I'll have some not so nice words to say to them. Until then, as long as no further information is available about what "God" may actually want us to do, I'll continue down this path indefinitely, and trying to be nice to my fellow man whenever possible, not because they deserve it, but simply because I want to be treated nicely as a person and not promote the suffering that is already far too common in humanity.
