Why do Russians see Nazis everywhere? Before going to sleep maybe you're checking under your bed to be sure that nazi isn't hiding? Not allowing athletes to participate just because that they're Russian isn't discrimination. It's collective reposnisbility. They're not directly responsible for war in Ukraine, but Russian citizens should respond for actions of their elected president, which was elected by majority of votes.
Maybe these things in Europe can be called Russophobia, but what else do you expect? That Russians will be liked and welocomed with a joy?
