This is the most ironically hilarious statement I've seen in a while. I don't know where this "white guy privilege" meme started, but I find it funny when "white guys" call themselves privileged. No you're just a human being and you just happen to live in a country where the majority is white people. If you go to an Indonesian cannibal tribe, you're just a food and no longer "privileged".
The reason I find that sentence ironic is you're talking about "do our best to help" but the sentence itself reeks of some sort of weird idea that you are above other non-white men and women. Statements like "You're most probably a white middleclass guy" is what hurts the people most, and you don't even realize that. I laugh out loud imagining if OP was a woman, she would be like "WTF is this guy". People don't "need help". The precise thinking that they need help is the first thing you need to abolish from your mindset if you really care.
