nationalists deny even documented facts.
So name orgnization people resposible for that (according to you) belonged to?
You see you are deep down stupid. If you clamed that was done by some Poles you could have get away with that as it is vague enough even thought we know it was done by Germans.
You just couldn't resist and added nationalistc - do you really claim that patriotic Poles were working hand in hand with Germans? If you mean memebrs of 'Endecja" you need to present us with names and proove they were part of the 'Endencja' or some offspring of it!
If that is a matter of the histrical reacord you should be able to do it in about 40 to 60 minutes. If you are not it will mean that you lie and slander again and you are just a shamless brazen liar!
