I think the argument that even if such things are selfishly motivated they can still be called love is invalid, because most people think it is love and like the notion/feeling/state of apparent bliss they are in, but what is really happening is they are deluding themselves into thinking it's love, ignoring the undertones to all these 'selfless' acts and thus declaring it love; or saying that even if they are selfishly motivated, why can it not be love? The answer is, it cannot be love, but it can masquerade as such and fool most people. I think that's what prompts that question/view. Reading that over, it would make little to no sense to anyone else, but it is so difficult to word.
In short, 'love' is love inasmuch as the actions are perhaps those of someone who loves you, but no true love is there.
For instance (utilising an analogy that plagued a female friend of mine lately, I'm a guy btw. Just saying as I read someone post thinking I was a girl...) a fake handbag has all the signs of a genuine. Same designs, same material (perhaps) yet it's not the real thing.
