Russian internet has a field day(or a month already really) of jokes that the GRU officers, which all are undoubtedly, in the Russian mythos, true patriots and heterosexual macho made in the image of the Putin himself, would carry out every order for the Motherland - to kill a traitor, to die for the Motherland, and even to truly practice homosexuality, all in the name of Motherland on the orders of "the comrade General".
The guys in the interview are obviously very bad at impersonating gays, and that follows pretty much the same outrageous "signature" style (the Russian saying is "sewn together using white thread" as it is very noticeable on any garments except white) as using "Novichok" and polonium (or assassinating major opposition leader right in front of the Putin's office windows) - all that is to make sure that there are no doubts about who really did it while of course officially denying any responsibility. Just like the signature killings by Mafia (which the Russian government in its nature really is) - everybody has to clearly understand who did it without the perpetrators and their bosses explicitly claiming it.
To the "the_grue" below - sorry, man, no offense, you just don't understand what you're talking about. Most probably you're just not a Russian.
Edit: you added that you speak Russian. Being a Russian and speak Russian are 2 very different things. That ridicule you see on the Internet is real, no doubts. What you don't get is that it doesn't make Putin ridiculous [deep] in the eyes of the populace and that it wasn't a failure [deep] in the eyes of that populace - and that is the main tragedy of Russia.
