We've only talked once or twice, and I don't know you very well, so I am looking at this from a neutral third person perspective with no personal opinions.
Evidence is showing that you have some immature sides to yourself, and I see that you recognize it and admit it. Immaturity is something that improves only from personal effort, not from outside pressure. I agree that you can improve over time and become a great, mature staff member.
People have strong and unfavorable opinions about you being a staff member, and they might be right. However, those are all created from the past and you cannot change the past no matter how hard you work.
I can predict that you have been really nice and helpful to people that you favor, and toxic to people who argues with you. It is very easy to become toxic. It is not so easy to redeem the toxicity. I understand that.
However, there are a few problems with you right now if you become a staff member, in my opinion. First, your playing time is really short, and there is no way that you can help so many people if you only play 1-2 hours a day. I can only play that much as well, and I agree that Minecraft shouldn't be the priority in life. However, more effort will be needed as a staff member for sure. Second, most of us new players have not seen you talk and help. Those "hi meep"s and "welcome!"s are really important in creating connections, I believe. Third, due to your inexperience as staff, I don't think you realize how much work and seriousness it takes not just to be staff, and not just to stay as staff, but to really help others.
I am certain that you will be able to become a great staff member. However, I agree with others that you need more time to help the community before you get the job. Therefore, I am a little leaned towards -0.5

PS: Polygamy has nothing to do with this. It is a social culture that should be respected, and not joked about. If both men and women believe that it is right in their culture, we have absolutely no right to judge them.
