I feel like the ban on Russian athletes has less to do with the drug users than it is anti-Russian sentiment.
Obviously. Just the petty and vile revenge for Ukraine and Syria. Doping? Don't make me laugh... yes, i can admit that Russians using doping too, but no more than US team, where nearly every athlete (433 of 450 doping tests, to be exact) is seriously ill and using doping "for medical reasons", with full permission of WADA.
As for "serious proofs", this is no more than opinion (well paid opinion, i can add) of one single person with no any material evidence. No any normal court would accept this. But since this all is about Russia, and to Western world Russians are new rogues and pariahs, everything is clear: the WADA report is full of phrases like "we can not confirm this, for obvious reasons, but this is clear that..." Such thing as presumption of innocence is not applicable too. All Russian sportsmen are now considered "dirty" by default and each of them should then individually prove that he, unlike other Russians, is "clean". And even if he somehow managed to prove this, he's still not allowed to compete under national flag and there is no any guarantees that his rewards will not be taken away one of two years later, for some new political reason.
And you know what? Go to hell with such "Olympic spirit". To me, this spirit is long dead. You, westerners, are the real antipode of king Midas, you're turning everything you touch into dirt and shit. Are you want to have your own puppet sport-related inquisition, to expell all the serious competitors (China will be next target, i suppose, the "investigation" already started and follows 100% the same scheme), to compete only with Latvia and Yemen? Excellent, good luck down this road! But everyone, including you yourselves, will know the REAL price of your records and medals.
As for Russia, there is good saying: whatever doesn't kill us, makes us stronger. Obviously, this vile slap will not kill us, but we (i mean exactly Russian people, not Putin with his team of oligarchs) will remember these slaps, for generations ahead.
