I was going to say they love all equally conditionally, but as I think about it I suspect that isn't true.
I'm leery about this kind of approach as it is neither practical nor is it particularly realistic. Plus, in a very real psychological sense, one is setting themselves up for failure and the guilt that will surely follow when they try to thwart nature with such a high ideal. By way of example, for the most part, I like most people I meet. I do not love them, though I frequently quite like them and find them charming for whatever reasons. The feeling is likely reciprocated.
On very rare occasions I meet someone
I have an instant (inexplicable) dislike for, it is usually an involuntary physical reaction and an emotion recoil effect. Something creeps me out about the person. Without exception when I was in a position to know someone like this better I began to understand why I had that initial reaction and it was again, without exception, for very good reasons.
I save my love for those who genuinely deserve it and who have earned it.
Likewise, I see it more as an act of naivety to treat all religions as if they were all somehow brilliant expositions of the nature of the human condition. Some religions have very wonderful core principles that have always been true, are true today and will likely be true forever.
That said, they also have their seamy underbellies that might be wise for any thinking person to avoid like the plague. Do we just sweep all the naughty bits under the carpet and pretend they are not there? Embrace those who quietly pray for our destruction or demise at the hands of their oh, so benevolent god?
