I feel that I am empathetic (or at least sympathetic) to the plight of transgenders, minorities and others who feel that they need an anonymous or pseudonymous platform upon which to share their views.
I am substantially less concerned with those who do not see that it is Google's right to offer a platform that requires real names. So long as there are other platforms available and allowed that support anonymity/pseudonymity, I don't see it as a great concern that one particular vendor doesn't work exactly how they want.
If the discussion were framed as a matter of law, and that a new law were coming down requiring all discussion platforms / social networks / blog platforms to use real names, I would be against that law.
It is within the rights of those providing the platform to determine what policies they wish to allow or disallow. It is within the rights of the users of those platforms to use or not use the platforms they agree or disagree with.
I do not feel it is within the rights of those users to demand (or at least, to get a result from the demands) that a platform change its policies to suit their ideals.
