I have not referred to the Councillor as a closet Nazi, i have said that it is only OK to hold those views if you are a closet Nazi - which does not implicate him directly.
I have no knowledge that the Councillor is a closet Nazi - but he certainly holds the views of one, which is not the same thing.
I am debating on a debate site as a private individual. The Councillor is holding forth with his abhorent views on a public communications site designed to diseminate his views to the wider public, and he is paid as a Councillor, and a political party member - I am neither.
That's why I get to 'carefully' state my opinion, and can back it up, and he is a thoughtless nasty-minded bigot who has been rightly castigated for his behaviour.
