Why does Stack Overflow have the wrong people working?

First, I thought stack overflow is best website because it helped me a lot to find my coding answers and solutions. But because of few stubborn people I am writing this dirty post. There are few people on stack overflow who has right to edit our post any time. And if they don't know answer or they're oversmart they close your post. They also make you angry and make fun of you in post and later delete it. So, others cannot see it. There should be a complete transperancy in post. So, everyone can see what is happening in background of stack overflow!. Yes I can understand that they make post unique so it's easy to find for everyone. But, there are many things stack overflow should understand and do not give access to any developer whether it is pro or noob cause they are idiots.
