I have thought more about this and here's my stance:
As much as I love MJ, I see a few problems with dating someone from the fans community. Here's why:
1) Throughout my fan life, I have come across several people that, despite loving MJ even more than I do, were not the people I'd love to hang out with because of their personal traits. They were selfish, unkind, self-centred, etc. The fact that someone is a fan doesn't mean they are the person you'll want to stay with for a few hours, let alone the rest of your life.
2) Although I love MJ very much, I wouldn't want to date someone who keeps michaeling 24/7. I don't do that either. I have some hobbies, I go to university, I try to make a career. I need someone who would broaden my horizons and with whom I could discuss things that affect my life. It would be hard if our only common interest was MJ.
3) Some things around MJ have been frustrating (trials, death and so forth) and at times, I just needed to completely withdraw and focus on something else. If I want to distance myself from anything MJ related for a while, I won't listen to his music, I won't log in here, etc., etc. With another fan sharing intimacies with me, it would be more difficult.
Now, I'm not saying I wouldn't want to date anyone from the fanbase. I would just to make sure we would get along well. I have been through a few difficult relationships and I don't want to make the same mistakes again.
