This kind of British values/patriotism is totally unnaceptable

Even with the wisdom of hindsight, after 100 years, and with the knowledge that 20 million humans were killed horrifically (perhaps, a total 100 million casualties) to stop Germany controlling Europe, we still all think, it was well worth it to be on the 'winning' side!!  Even, when it was a Pyrrhic victory, too leading onto the 1939 European and global war.
