Wow that is truly retarded. I'm sorry but if anyone gave you money for that it should be money they never expect to get back.

I hate to be so hostile towards your idea but there is actually such a thing as a dumb idea and it's useful to point them out as such.

There are dumb ideas, and it can be useful to point out their weaknesses in a constructive manner. However, using the word retarded to describe something in a negative way is both childish and derogatory.

Here's an eloquent description of why what you said is inappropriate. When saying retarded, “What we mean is that he is as stupid as someone who is mentally handicapped, and we mean that in the most derogatory sense. The implication is that the only characteristic of mentally handicapped individuals is their stupidity."

Don't take his use of the word "retarded" so literally. People might take offense to the word but understand that he doesn't mean it as an actual slight toward people with real mental disabilities.

Have you considered that you weren’t chosen because of your attitude instead of your project. Your comment here (as well as your name...) betrays a certain... outlook on the world.

It's not just about the ideas, it's also about the team, the people at YC have said as much in their press releases of the past. I would look inward before looking at your project.
