Sorry, that's not how it works. You have to prove that your source is real. That is called validating your claims. Otherwise, you have nothing.
And to prove your source, just show us the original source. Not just find some other apologist site that also uses the quote.
For example, in a recent debate in here I had stated that the Japanese were horrific occupiers, and even beheaded civilians as a sport. And of course the idiot tried to scream that it was all American Propaganda, and it was all lies.
Until I actually provided the original Japanese newspaper clippings, from Japan, which were reporting the contest between 2 officers to behead 100 people like it was a baseball game.
Now surely if that bit of newspaper could be found after Japan was ravaged by war surely the same can be find in an England that was much less ravaged. In fact, that is not the first article of the event that has been discovered. That is one of the later ones announcing they were tied and going into "extra innings". But wow, for some reason the one you try to quote does not seem to exist.
That is why nobody takes you seriously.
