I've replied this many times on Twitter in Russian

11. I often zap trolls in Russian on the WaPo site, too

Also, when right wingers post in Republicanese (using an apostrophe to form a plural, etc.), I tell them welcome to the USA, and that since they are obviously new immigrants who never went to school here, I am glad to help them by pointing out that English does not use an apostrophe to form a plural. If they get pissy, I point out that they gave themselves away because there is not one school in the entire English-speaking world that teaches using an apostrophe to form a plural, and they should accept that there is no shame in admitting the obvious--that they are recent immigrants whose English is far from perfect. I can't say "immigrants from Mexico," since Spanish doesn't use an apostrophe to form a plural, either (although I guess the likelihood of a Republican troll actually knowing that is probably close to zero).

The fun thing about the Post is that it is read by all sorts of State and Defense people, many of whom understand Russian, and give you numerous likes when you zap trolls in Russian.
