That is your impression. You seem to be relying on word of mouth i.e. the general public representation of what Kickstarter is. Unfortunately that is not accurate.

Simply reading FAQ will shows they are not a store, quoting:

At the same time, backers must understand that Kickstarter is not a store. When you back a project, you’re helping to create something new — not ordering something that already exists.

you might think they are( a store ), but that doesn't make it true.

That is completely situational. They are what they are. If you ignore the contract/FAQ it is only your fault. You seem to do so, which is great, but slandering is not honest.

If you agree that the language you are speaking is English we all speak, then it is certainly a form investment or funding.

You are making an assumption that investment guarantees some stake, it doesn't. You only get what is in the contract.

Why are you singling out Kickstater? You statement holds true for any form of investment.

There seem to be a misconception what Kickstarter is. Their FAQ is clearly explains it is funding. I'm sure if everyone who backs a project would read it, there wouldn't be so many complaints.
