Why does the media make it seem like I should support the black community because I am part black?

Half of the issues that these "community leaders" endorse could be solved by placing more of an emphasis on personal responsibility. I hate it when people say successful black or part black people need to "share the wealth to uplift the community" or be labled a sellout or self hater. Someblack people call me a sellout because I don't support every black artist, politician or athlete. People question me constantly because I am more conservative and I disagree with 90% of the things Obama has put forward I like to avoid any conversations on politics because of this. Anytime I am out with my male friend(who is white) people ask if I am a "self hater" or why I am dating a white man. I am tired of this type of garbage, most of these people preach anti racism, yet drag race into every single conversation. I have known some of these people since middle school and have stopped talking to them, because they cannot accept my views, dating choices, and how I choose to self identify as mixed. My dad is black and asian and deals with the same thing, and people have said that my mom is "racist"(which is not true at all) because she is not a democrat.
