How about instead of asking us for permission just so you can look good when you donate (even though you've supposedly donated $1500 already, which I highly doubt), and instead of begging me for rep just so you can feel better about yourself, and instead of being an all round faggot, how about you just donate to a local charity without saying anything like most people do, because only attention whores actually tell people they donated. Fuck, you're even worse than that, you're bragging about the fact that you might donate if we give you a good enough reason, as if we actually want to give a shit about your pathetic attempts of pretending to be charitable.
Hmm, donate it to a smaller charity, like seriously.. Everyone says "don8 to cancer guys" when really they get enough donations, they would most likely spend more money on advertising than actually research. Like seriously think about it. Donate to a cause that's close to you, or if you know of anyone who could need the money.
You could even walk up to a homeless man and take him out for dinner. The amount of ways you could make someone's day with $100 is limitless, just be creative!
