Would atheists and theists get along better if that where the only difference?

What am I talking about here exactly, well…

To be an atheist, there is only one requirement, no belief in gods. other than that, there are none. When someone tells you they are an atheist, all you can tell about that person is that they dont believe in a god. likewise, when someone tells you they are a theist, all you can really say about that person, is that they very most likely do believe in a god, as well as following a specific religion.

However, that is not really the only difference is it. If you are an atheist, even though it is not a requirement of any kind, there are trends and patterns for how atheists think. for example, even though there are plenty of conservative atheists, at the moment at least, there seems to be a much higher number of liberal atheists. likewise, there seem to be a lot of conservative theists.

When someone tells you they are an atheist, you can only really say for certain that they dont believe in a god. and while it would be wrong to make any other assumptions, you can kind of, if not assume, suspect. that perhaps they are also enclined not to believe in ghosts, conspiracy theories, they they are more likely to believe in alien life, that they are maybe liberal, that they are probably in favor of legalizing cannabis, in favor of euthanasia, and a whole load of other things. and while you would be making an assumption and a generalization, you probably would be right.

So, do you think, that there would therefore perhaps be less friction among those who believe and those who dont, if that where the one and only difference?
