Mark Zuckerberg builds walls around in Mansions in San Francisco and Hawaii to keep out unwanted visitors

During the recent election Facebook founder, Mark Zuckerberg, a severe critic of Donald Trump's plan to build a wall across the southern border and a top donor to the Hillary Clinton campaign forgot to mention he had a $10 million estate in San Francisco around which he built a wall to keep out the tens of thousands of undocumented aliens freely wondering the streets of that sanctuary city.  Now to compound his hypocrisy this billionaire has built a huge 6' wall around his massive Hawaiian estate.  A wall that would not only keep out those Mexicans who managed to swim to Hawaii, but one that also blocks his neighbors view of the Pacific Ocean.  Zuckerberg is proving he is no different than other coastal elites who feel they are above practicing what they preach.  They fall into they well established class whose motto is: "do as I say and not as I do"!
I would be the first to say, there is nothing wrong with a man building a wall around his home to keep out unwanted visitors.  But then I would also be the first to tell you there is nothing wrong with a nation state building a wall on it's border also to keep out unwanted interlopers.  Walls that keep people out are welcome, however walls that keep people in (the old Berlin Wall) are another thing.  But even there, there are some exceptions---prison walls are just fine.
