The Russians are trolls

I am informed by "The Week" that the Russians are responsible for fomenting fear and anger on the Twittersphere by infiltrating Western Tweet networks with non-existent, but influential tweeters and producing hate tweets against those who voted Remain, for example, and I think they were pro-Trump too. I can see the point of this. It makes everyone feel sad and upset when they find so many of their fellow countrymen, who had seemed quite harmless or generally quite pleasant, were actually bigoted and sociopathic. It dilutes feelings of community and trust. It's effective, but it gains them nothing and it is wrong, in the same way that killing all the tigers is wrong, and deep sea fishing is wrong. It erodes the world's good nature, which took a very long time to develop, and will not be easily replaced.
