I think I get this guys' point, and honestly I completely agree.

Everyone does this every time.  Everyone's always trying to affect elections, including American elections.  This isn't news; it's common knowledge.  Russia was trying to affect American elections last year.  And it was the year before that.  So was Britain.  So was France.  So was Germany.  Everyone has an interest in everyone else's affairs.

In other words: you know this isn't news, right?  It's always been happening since the dawn of nationality, and it will keep happening.  Focusing on this one time Russia did it is the height of folly.  They did.  They'll do it next time.  You'll do it next time to them, don't worry.  Canada will mess with Guatamala's elections too.

What's the solution, if I haven't lost you already?  Ignore it.  Tell them to stop, and go about your day.  It doesn't even work most of the time.
