That doesn't mean that she do it intentionally
There is no exception in the rules of WADA, CAS, or any other relevant agency here for "unintentional doping." Look at what happened to Jessica Calalang for one of many examples.
We are talking here about a case in which an extremely prominent figure skating coach and her team offered a defense to international regulatory agencies that Valieva accidentally ingested TMZ from her grandfather's water glass. That was literally their argument. And apparently they chose that instead of arguing that the TMZ was baked into a cake.
Here we have people arguing that the doping was unintentional or conspiratorial, as if rabid Alena Leonova fans were hoping for her to come back and make the Beijing Olympic team by taking down Valieva, using lax security at Russian Nationals as an opportunity to spike her water/vitamins/whatever she ingests with TMZ. Because, clearly, if someone wanted to spike a drink with materials banned in skating, they would choose TMZ of all things (I guess these fans are too young to remember Meldonium?).
This point has already been made above, but of course the people who intentionally doped Valieva should be investigated and, if found responsible, punished. In no universe is that incompatible with agreeing (or partially agreeing, or disagreeing) with Valieva's ban and the reallocation of the Olympic team medals.
Instead of conspiracy theories, whataboutism, and giving the benefit of a doubt when a doubt objectively doesn't exist, again I emphasize that grandpa's drinking glass was literally the defense here. And if the real problem is the focus on Kamila rather than who doped her, maybe talk about that instead of insisting on her innocence and unfair punishment, and excoriating skaters who have been waiting for years to get medals of any color for "gloating."
