Sure, I can make it real simple and just explain the concept.

I don't believe I'm responsible for stuff that happened hundreds of years before my birth; that's a dangerous precedent to set and leads to rampant persecution of entire nations (like you inciting violence upon British people for example, and feeling like that's an okay stance to take).

As for current events, I believe we do have a responsibility to call out and work to correct any injustice at every juncture, and pride myself on trying to doing so. That being said; much like you haven't magically fixed the persecution of aboriginals in Australia, or Israel's persecution of Palestine (which Australia is complicit in too btw...) ; there is only so much we commoners can achieve.

So instead of flinging muck at 70 million people because of their nationality, try finding common ground. Your abrasive nature serves nothing but sowing discord.

I appreciate this will likely fall on deaf ears, and you'll probably resort to further projecting of your own feelings of frustration, so this is the last time I attempt to appeal to your better nature; I'm not fortunate enough to be retired, so I can't waste any more energy on attempting to help you see reason.
