After WWI, during peace conference he advocated independent Germany united with German speaking parts of Austro-Hungarian Empire. Of course cut on the east in the favour of Poland. He was generally in favour of every nation having its own state. Nothing about 'Untermenschen' for sure, same about the Jews.
Well...I got another impression...but then...my knowledge comes from wiki and polish-youth mainly :(
What about pre-war Britain or France or USA then? They had a developed industrial sector (Britain started the industrial revolution) and they didn't manifest similar behaviour like GErmany did.
What behavior? How do you think became Britain the empire Great Britain???
Do you think they conquered 1/4 of the world talking nice?
And that the US even fighted the war with segregated blacks? Race laws full in action???
Hitler was full in tune with the Zeitgeist....he just took it to the extreme and became a
rival to said Great Britain and the US!
BTW: Things change quickly in Poland. After a few decades you will find hard to believe how Poland developed (At least if we don't enter the euro-zone to soon, heh)
Well...of course you will....you get lotsa support from Germany, heh.
But anyhow, we were talking about a time more than 60 years back. And even as Dmowski and Hitler were not that different, a Dmowski would had had not that much possibilites to disturb the balances in Europe as a Hitler with Germany had.
