If they were all carebear, snuggly non-violent people, then Subhas Chandra Bose would never have been arrested. You remember, that guy you called a "freedom fighter"?
If there were no violent incidents, there would have been no indictments (remember- British legal system?) If there was no violence, then there would have been no arrest. Oh BUT WAIT! Look! He didn't agree with Ghandi! So that gives you an F in history, an F in logic, and an A in avoiding entanglement with violence through fast talking - but an F in reading as you didn't understand that I made a proviso if your great grandad DIDN'T fight - and he didn't if he was non-violent. If he did - then he was a terrorist if he didn't have a uniform
You say he gave up a government job - that means he was an educated man. Therefore - he KNEW what was going on in Europe. He wasn't "unknowing" or ignorant of the outside world. Don't spread that self-serving "pity me we were poor" fertilizer here. If he was as you describe, a civil servant who quit - then he KNEW what the Nazis were all about. The fact that you make such idiotic comparisons without understanding the depth of evil the Nazis achieved ("some guy called 'Hitler' and his 'Nazis' for the terrible things they did to some people called 'Jews'") shows that at least one thing is true - he obviously failed to educate you to his level. Or you've been indoctrinated in some sort of nationalist pseudo-fascist doctrine.
It's like you are comparing stubbing your toe with cannibalism. It's sick, absurd, and revolting for you to go on whitewashing Nazi atrocities and comparing them to British misdeeds. That's repulsive and simply stupid.
