Why americans don't respect freedom of speech? Why americans don't permit other people express other ideas?

YA is not a free speech area. They can do whatever they like, and usually do. If they do not agree with your answer they can remove it. You have freedom of speech in the US but YA is owned by Yahoo and they can and do delete things they don't like. Yahoo answers: your questions answered by thousands if you have the same view point as YA. Otherwise YA will delete it! ME = working at keeping under the radar!
