Well, Israel has made it easy for people to dislike them. Just to be clear on my position, I hate the Israeli right-wing government, not the people themselves.
I have no problem with naturalized athletes competing for other countries. My only problem is rich countries buying off talent for poorer countries. Otherwise there’s not much you can do. Plus, many people, like @heywoodu I believe, like individual athletes and not the flag they fly. I’ll admit that I mostly cheer for certain countries over athletes, but generally I support individual athletes too.
These guys had a dream to go to the Olympics and they succeeded against what at first were thought to be better teams. I’m very happy for them.
