Why is limiting campaign donations and thus limiting what some falsely call "free speech" a bad thing? I cannot go to my local elementary school on a nice day when the windows are open and stand on the public sidewalk and scream sexually tinged obscenities at the top of my voice. I cannot stand up in a movie theater and began my own political speech. I cannot take out a full page ad in the local newspaper telling lies about people in the community and destroying their reputations.
Why: because all right have limitations and boundaries.
And so should big money buying politicians and elections.
