Take on the Russian curling doping scandal

Wait, the Russians competing under an Olympic flag because of doping got caught for doping again and this time it's for curling. I'm not sure what athletic prowess benefits a curling player but I'm assuming whatever it is, it's something that improves with steroids because otherwise this would be even dumber.
The Russians are a completely crooked bunch, they cheat at curling and our president doubts they tried to influence our election?!?? Open your eyes..what the heck is wrong with you people
