"the men then had much less problems to express their FEELINGS for other men than the men of today"

I do agree. And you're right: when it comes to the works of art or actions taken by historical persons, sometimes their traumatic childhood/homoerotic feelings/unrequited love/whatever is a key to understand the above, sometimes matter a little and sometimes not at all. Supreme Being protect me from scholar manierism and fanaticism puting one methodology above another ones: I am far from explaining everything via psychoanalysis.
