Speaking from experience, people in Ireland are overwhelmingly pro-palestine.
There is this user in the comments: https://www.reddit.com/user/EntireCourage308/
Its a nearly year-old account, it started posting about a month ago, it made some innoculous posts, then pivoted to posting far-right misinformation in the r/northernireland subreddit.
Looked at the front page earlier today and one of the top things was an AI generated video of POC trashing NYC. Comment section was an endless chain of “democrats hate America” and “we imported the third world”.
