Well, Battle of Britain was a major battle in WW2 and especially to Brits and it's allies it was a show of strength and determination. It had large scale aerial battles all over southeast England and ultimately over London. It decided the fate of Britain and possibly outcome of WW2. So no wonder some members might be a "bit" pissed off when CoD came out in a state it was in and now the sequel decipting Great Patriotic War with features CoD will never see, adds to the insult. Does it warrant rudeness? No, but no need to go with the crowd and dish out more rudeness
Anyways interesting info filtered out there from the intended puns and all. Bring on the next series of answers.
