Good question. Some say boycott the whole show or just Israel’s song, I suppose you can boo if you’re on location or be loud in the chat on the official livestream, generally use the buzz on social media. Generally, they will be aware that people will want to register their disgust and will probably prepare themselves for that.
I’d say generally, participate normally in Eurovision discussion and then make noise or boycott when it’s Israel’s turn. The media that love to report on the event, as it has a reach bigger than the Superbowl, will pick it up when it’s enough noise.
Also watch out if some of the artists will say or do something. Iceland is always very itchy and gives no fucks.
Where can I report this for drug promotion?
