I want to start a anti union organization. What would be best type???

I don''t think a Non Profit, Pac or a Super Pac works??? Is a For Profit LLC Crazy?? All of It''s Income will be donations and I feel Donner anonymity Is critical. (for fear of harassment) Thanks Mike Additional information My goal is to educate the 50% of the public not very knowledgeable of public policy. I think the time is right to reverse some of the Union corruption and gains they''ve made in the last decade. The list Is Long!! Lets start with stealing our kids education, elections and most of the states revenues just from Union leader greed. I feel the same way about politicians. (another subject) I think the current Is flowing In the right direction to make It fairly easy to pick off the low hanging fruit with just 4 fairly simple steps. I also believe great support exist for It. I would be willing to do the heavy lifting and be the target of Union Thugs. Thank for your time. Can you help??? Mike
