The only relevant issue is the question as to whether all Russian citizens (regardless of ethnicity) should be banned from these kinds of events (more generally: have sanctions and sanction-adjacent actions taken against them), or just those who have directly contributed to the invasion (Putin, his military advisors, some Russian oligarchs maybe?) - which is a good topic for discussion. Claiming "discrimination", on the other hand, is factually incorrect, blatant emotional manipulation & unnecessary flamewar-bait, and does not belong on HN.
