Fundraising: essential for social change, or harassment?

I Just posted the following on a discussion section of a bbc article about fundraising:

  I'm a fundraiser and people who complain about being harassed clearly have issues with setting boundaries in their own life and, (very unfairly in my opinion), charity fundraisers seem to bear the brunt of these people's frustrations.
  Assertive, healthy people will either stop or not, and smart people will have a joke and a laugh with us. Many people seem to think that because we're in the street attempting to communicate with people that this makes it ok to load any outstanding social frustrations onto us. Nobody vocally objects in the street to advertising everywhere you look and "price drop tv", macdonalds, betting shops and the commodification of an entire society, but because we're stood there and vulnerable we become targets for all kinds of bigotry and discrimination.
  I am a fundraiser because it's a good way to earn money and because the charities I fundraise for are trying to create a better society for everyone. So before you criticise us, try standing in a busy town centre and asking people for time to talk about something you're passionate about. Try being the change you want to see before you criticise others for their attempts.
  Charities only exist because our society has great gaping gaps in it. The societies to come will laugh at the idea of special organisations to "protect human rights", "stop child abuse" and "halt the destruction of the rainforest". In my opinion we will always need charities until mankind learns to live with itself more harmoniously. So, here's an appeal to everyone to stop blaming and complaining and instead, start using all that energy to start creating the kind of change that they want to see in the world.

9 Weeks on the Streets

  Well... there have been worse jobs. 6 days a week, in a different town centre every day, persuading absolute strangers to contribute financially to the preservation of the rainforest...

"yo G, Whatup!?"

  Within the space of 9 weeks I have cried several times in the street, lost my temper several times more, nearly quit about 5 times, I have been thrown, week after week, from one end of the country to another and back, by my company office who have no respect for my Sundays. I've written a letter which got my team leader unceremoniously fired, had a great flailing argument with the Halifax about my "SURPRISE!" new overdraft fees, and wilfully engaged in a game of unrequited love, which I was only ever going to lose from the beginning...

ouch...

  On the plus side, however, I have cleared most of my overdraft, i've had numerous adventures, some more romantic than others, meeting old friends regularly and getting more time to hang with my little sister. Plus i'm earning enough money to be debt free in about 4 weeks time and still have enough to get myself a shiny new smartphone so I can use the internet wherever I am!

  All in all I can't complain. I'm going to a blues festival this weekend and working in the beautiful Isle of Wight again next week. So, hopefully without sounding too cliche, I'm going to finish by saying that the best thing about this job so far has been creating a good support network and realising what great friends I have...
