I agree and I can't believe people don't understand this basic concept.
I have some understanding of it - they view anything attached to a political group as 'corrupt' and sort of mindlessly supporting a group, and value their 'independence'.
But they fail to understand that, like the jail inmate who doesn't like the idea of joining the gang of his race, that that 'independence' can be very expensive and leave them powerless and trashed by the people who do organize, as organizing is power; and they fail to understand some of the better things that can be done with an organized group.
They'll look at a lot of things and praise them - say, the civil rights advances - but not appreciate how essential the political process of organizing was to their happening.
Without that organizing, we could easily still have segregation today.
Political operatives love the 'independent' as easy to manipulate; and the 'independent' who throws away their vote serves the interests who buy the other votes quite nicely.
You can go to an occupy protest and say "man, I really don't like these people", and want to leave - and then remember the cause you are united with them for and that leaving is to leave the problems without the people trying to improve them, and you get a lot more tolerant of the people and appreciate their effort. "Politics makes strange bedfellows" I think was said hundreds of years ago about this, because of the fact that these alliances are very important. If they want the luxury of not having them - they lose out.
And in fact, the special interests who do organize sometimes love to encourage this 'love of independence' and hatred of political groups, because it serves their own interests.
You don't see people like Karl Rove hating political organization - because he uses it to have great influence in elections, for evil in his case.
Fact is, these organizations are basically necessary because the 'other side' you disagree with is going to organize - so you can also or let them win.
It's a bit like corporations who love to attack 'socialism' if it's for you, but are thrilled to have it if it's for them.
People need to get over that repulsion to parties - and instead try to fight the bad things they see in parties and make them better.
Joining a party and supporting it does not mean you cannot disagree with it or that you have to be 'corrupt' and support it 'right or wrong'.
John Kennedy once said, faced with the demands of Democratic operatives as a candidate: "Sometimes party loyalty asks too much." Right is more important than party.
