I don't think that's the situation today. People are not treating Bivol as the enemy. It's just that putting Bivol or any Russian athletes into something uncommon treatment (not a bad one) will put pressure on the Russian President as their sports representative and athletes are now affected.
Yes, it's 100% unfair to the Russian athletes as most of them are also against the ongoing conflict but most countries are doing their best to slow down Russia as this war is a sh*t and the conflict is just between the leader's pride and not country vs country.
Regardless of the venue, the fight will surely generate big revenue. Both boxers' names are big in the boxing industry and there will always be fans that will spend money to watch this fight. Champion vs Champion, it will be jampacked.
The T-Mobile Arena in Las Vegas will surely be packed by the supporters of Bivol and especially Canelo. No doubt about that.
The hatred calm down because people are realizing that a lot of Russians are not supporting Putin's. So when it comes to sports, everyone should be equal. I don't think they will change the venue as the fight is about a month from now. People who want to watch need to book their flights/tickets. So would be a mess if they will change the venue last minute. I believe, they won't change it anymore, unless very important consideration is on hand, that changing the venue is the only solution.
