That would be my question as well. Michelle may have made a mistake purchasing the property in the first place without considering her own fears about the management and the neighbors.
I am also feeling from her posts and language that she may be stereotyping these people as "bigots" without actually knowing them.
While she may be able to stay in the park by using anti discrimination laws, her life there may turn out to be unpleasant because of it. It's possible to legislate actions but it's not possible to legislate attitudes.
BTW: The fact that her wife lied to the manager is not going to help her case. "That's my husband, he's is a crossdresser." would have been the appropriate answer.
