With an asterisk over 'unconditional,' I agree with everything you just said. Pretty sure that's one of the signs of the apocalypse

But none of that changes the fact that shallow, conditional, selfish love for others is still love, simply because that's how we use the word, and because that's where all love begins.
Less conditional love is something that takes practice and effort, constant self-reminders that most liberals aren't shitheads to pick just one example at random; it takes constant self-reminders of our shared humanity and shared fallibility, searching for the logs in our own eyes while trying to see things from others' perspective, trying to see the best in them or at the very least to understand the circumstances or genetics or brain chemistry which might have contributed to their current status.
Meanwhile truly unconditional love is just as much of an idealization/fairy tale as love-at-first-sight soulmates, and just as much a risk factor for making the 'perfect' an enemy of the good; think of all the abuse victims who justify remaining with their abuser under the belief that they should love them unconditionally, unaffected and unaltered by the abuse. In fact when you really think about it, truly unconditional love makes even less sense than love at first sight: "Would you still love me if I turned into a mango?" Of course not, if nothing else love is obviously conditional on personhood, or at the very least on sentience, and as with abuse there are certainly other conditions which should at least have
some effect on love, shouldn't be unconditionally accepted.
