It is Marching Season in Northern Ireland, when Protestants hold parades, marches and bonfires celebrating a Protestant victory over Catholics in 1690. The season runs from Easter to September, but the peak is in July.
This effigy is definitely a product of ultra right-wing talking points and mounting tension from anti-immigrant sentiment. It’s not a healthy expression of a valid concern. There are mannequins depicting human beings at the top of the pyre. Under it is a sign that tells you exactly the group they want to harm. Further, a sign that says “veterans before immigrants” sets up a false dichotomy that pits two unrelated groups against each other. It has all the tropes of this type of propaganda.
The designers and builders of the pyre should not be celebrated and should face some legal backlash.
It’s like South Koreans call themselves Koreans, because culturally North Koreans aren’t Koreans to them. It’s not culturally sensitive and by no means do all South Koreans do this, but I think most would understand the reference. Similarly, the commenter is saying that this isn’t happening in Northern Ireland, but just north of Ireland. Wink wink.
