i don't think you get it why would it be biased when no one is trying to exclude counter examples as i said if you find any counter example go ahead and include them no one is pushing any pov except maybe you which is what it begins to sound like you are reading too much into this when us presidents reaffirm the one china principle they are in accordance with their country's official policy it's not a mistake nor does it create controversy when the vatican invited only roc president to john paul ii's funeral but not prc officials it was also done according to its own diplomatic policy there is nothing controversial about that like i did before i've always said mistake isn't the right word from the get go nor is it slip of tongue instead of going in circles and nitpicking why not just change the title diplomatic controversies or something
