I wouldn`t take the 'stepping in' to personally. I don`t think it`s about you being a child ( I understand you said you FEEL this way, not appear,..) so much as the fact that some people just don`t get it until they are out-numbered.
This happens to all walks of life. It`s the negative version of the 'voting system', and some don`t see the error of their ways until more then one person comments, reprimands, etc.
Once out-numbered, or out-voted they back off. We all need back-up now and then.
