Kurfurst tried to portray any and all British aircraft as useless hunks of garbage while never admitting to any of the shortcomings of the German aircraft, frequently outright lying about capabilities.
In one long bomber thread that turned to Mosquitoes, he expressed doubt that any Mosquito pilot aced while flying the Mosquito. He maintained that the Me410 (I like the Me410) had a much greater effect on the war and when I posted 418's record to refute the lack of Mosquito kills claim, he stated that 418's record proved how useless the Mosquito was and that any German unit would have far better record. That was pretty much when I was done with him. It really is a shame though as it would be extremely nice to have guys around who are as strong with the Luftwaffe as guys like Dan and Widewing are with the Allied stuff.
He either has an extremely bad grasp of history outside of the Luftwaffe units while thinking he knows it all or he knows he is lying and does so anyways. I'll leave it to you to decide which is worse.
