Looking up other Turõgins in Estonia, they all have very obviously Russian first names and zero obviously Estonian names.
There's no doubt that Ivan Turõgins parents fully intended to give him a Russian name, even if Estonia requires Estonian script on Estonian identity documents.
Even Estonians call these names "Russian names", that's what they are. If someone in Estonia decides to name their kid Muhamed, that doesn't magically become an Estonian name.
> Calling Estonians Russians is not taken well at all
I suspect that your comment wouldn't be taken very well by Estonian Turõgins
