Ireland is cracking down on free speech after a stabbing incident in Dublin. Former UFC champion Conor McGregor is being investigated for his social media posts criticizing the country's response to the incident. The case brings into question Ireland's new hate speech bill, which critics argue is an attack on freedom of speech. McGregor's comments would likely be illegal under the proposed law. Immigration tensions in Ireland have been high due to the country's record-high levels of immigration.
