What cultural faux pas should I try to avoid making in Dublin?

"It is important to be mindful of cultural differences when visiting Dublin. It is best to avoid making negative comments about Irish culture, history, or politics. Additionally, it is important to be respectful of religious beliefs and practices, as Ireland is a predominantly Catholic country. It is also important to be aware of local customs, such as not wearing shorts or revealing clothing in religious sites. Finally, it is important to be aware of local laws and regulations, such as not drinking in public," remarked another expat who made the move to Dublin, Ireland.
