Ok. Valid reasons for not moving. And I'm truly sorry about your condition, because I lost my father to cancer back in 2006, as well as a very close first cousin. But it sounds like your handling it well.
Lastly, there are varying degrees of "getting along", and different people would define "getting along" in different ways.
I frequently see individuals in public from different races on a regular basis socializing , however that is primarily younger people, under 30. My 18 year old grandchildren have a very diverse group of friends, and they are frequently at my house.
Those of us who are old enough to recall the years prior to the Civil rights movement regardless of race, will likely always be skeptical of what progress really looks like to an extent.
Thank you for your sympathy, it's very well appreciated.
My point is that yes, the internet allows us to hear what an adversary thinks without retribution such as violence, but unless somebody makes change, very little progress will be made.
People of different races can live together in peace. People of different cultures can't, and that's what we are really talking about here, culture and social status, not race.
For instance, when my area was all white, I would simply cut my lawn and tree lawn. Today I have to remove all the garbage from my tree lawn before I can even think about bringing out the tractor. This is an acceptable environment for many blacks but not an acceptable environment for whites. During the work week nearly everybody went to bed or went into the house and respected other peoples peace so they could sleep and get up for work in the morning. Now we have people driving around at midnight and later with their music blaring so loud it could wake up the dead. This is an acceptable environment for blacks, but not for whites.
So it's not a color issue, but a behavior issue.
True story: Years ago my closest friend hit the lottery. We were in our early 30's. He was still living with his parents and of course, wanted his own house and asked my advice on where to move next. His real estate agent got suspicious because her client was a long haired jeans wearing yahoo with no job who's intent was paying cash for some of these expensive homes. He finally had to explain his situation so she took him a very wealthy suburb to show him some houses there.
He loved the house she showed him but was very uncomfortable. The neighbors were outside talking and their jaw dropped when he exited the agents car to look at the house. He said these people walk their children down the street still dressed up in their office clothes. He could have easily afforded the house, but knew he would draw great concern from the neighborhood. These are people of his own race, and I'm sure some of his same ethnic background, but he could never fit in with his lifestyle. He opted to buy a home where I suggested.
