In my opinion, as an international community, we should put pressure on Russia in every possible (peaceful) way, so boycotting their casinos is, absolutely right!
Have you ever thought that Russian citizens agreed to this attack? almost all of them refused except the president and parliament
I'm not against this boycott but if you think rationally you should know which one is the most appropriate.
If this way can stop the war I will support but if it doesn't have an impact I think this is a misdirection.
