Do you honor birthdays with charitable giving requests?

I’m referring to the “please give to this charity for my birthday” social media posts. I ask because the requests sort of rub me the wrong way. First, it implies I should give a gift when I might normally just wish them a happy birthday or send a card. Second, if I have already purchased a gift, now I feel a little wrong in giving it. There seem to be layers of guilt and expectation that go against the spirit of gift-giving.
