Isn't that the standard reply of the haters whose rantings have been unmasked through facts?
However... there is another possibility. It is possible that you truly believe all the junk that you have been spouting because that is what the Polish schools have taught you. It is unfortunate, but most nations tend to rewrite their own history after the fact in order to cover up shameful behavior and let the national concience live. For examples, you can turn to Western Germany and their crusade to debunk the Holocaust.
I can also understand why you have not bothered to verify your education through "other" sources. It would cost a lot of time, effort and perhaps pain at shameful discoveries. With these words, I put down my sword with you. I admit I have no clue what you are talking about re "Tudjman", and I will now take the time to find out that was all about.
I sympatise with you and I do not want to shatter your illusions. Not looking up this Tudjman issue (and others we discussed) will certainly save you from "pain at shameful discoveries".
