Charges that he did not theorize.
Now, as for Trono e Altare, I don't know it; anyway I have no proof that Mignini had any link to it. There is only Spezi's claim. I'm rather sure Mignini has no contact with them in the present times.
I knew instead that for a while he had contacts with the group Alleanza Cattolica, which is a group that I happen to know. It can be defined as a Catholic fundamentalist assocation (their views are not different from those shared by many US Republican congressmen). Basically their activity consists in having an ideological journal.
I knew that Mignini had contacts with the group years ago and he wrote one article that was published in the journal; since I was curious, I searhced read Mignini's short essay. I found the article had nothing actually religious, nor ideological, nor extremist. It was an essay of local history. I discovered that Mignini's hobby is local historiography.
I hold the views of association Alleanza Cattolica as politically unacceptable or anyway wrong and incompatible with mine.
However, what I see is how these topics are totally pointless. We are not interested in Mignini's political views. I don't share political nor philosopical, ideological views with millions of people. To me, the fact that a person attends Alleanza Cattolica is something that does not sound 'good' about the person because I'm not sympathetic with that association.
But other people may not be sympathetic with other groups and parties.
It is also objectively very easy to attack someone because he overtly attends or attended unpopular groups or has unpopular political views.
But this does not actually have any logical implication.
Moreover, it is pointless if you consider that Knox was prosecuted by Manuela Comodi who is a leftist, the president of the local syndacate of magistrates and close to the Democratic party. Judge Paolo Micheli attends a Communist Party. Giulia Bongiorno was the member of a conservative group leaded by a former neo-fascist, while instead Pratillo Hellmann is a right-winger and supporter of Berlusconi. Dalla Vedova's brother is a parlamentarian in a very moderate centre party, but was a former comrade of Bongiorno.
All these lables are misleading and superficial.
Just if you walk trough Perugia, you would see that Mignini is highly popular. Very much trusted and respected, and regarded as very honest.
This, is not because Perugians are Catholic, nor monarchists. In fact, most Perugins are not Catholics (and nobody is a monarchist).
