Not all that long ago people would have said that no gay person (openly gay that is) could be in government representing the people and no gay couples would ever be able to marry.
Mind you at the same time they would have also said no black person would be in a government position, they are a second class citizen as they were told to go sit up the back of the bus, not forgetting disabled people, both physical and mental issues were locked away behind closed doors, not often seen in society.
Had we suggested way back then that a black man would one day be in the top job they would have locked us up in a mental institution and yet even more amazing had we said a man with mental issues will also made it to the top job, although some would claim that is fake news. No way would have been the cry. Who knows what tomorrow brings and to be honest, could they do any worse a job than the current crop.
