"So you want a double standard then?"
Why does any standard have to apply?  There is no sense of "fair" in international politics nor is there a police department.
"Why don't you go protest about all the things the US is doing in other countries that is so much worse than Russia giving people things to post on Facebook."
Because I know better than to waste my time on such relativistic idiocy.  I could argue concepts like "American Exceptionalism" or even just simple patriotic self-interest but it seems you function under some gross misconceptions.  You don't see Trump or any of his officers and executives giving back the millions or billions they earned taking unfair advantage of others, even their fellow Americans, from underpaying basic labor to gaming federal taxes yet you believe anyone owes the rest of the world "fair play" to intrude in US elections, politics, etc.
