All of them, if sung to the wrong crowd or in the wrong pub. Know your audience. While serving in the army (British, dammit) our little group of piss heads used to love to hear Kevin Barry sung by our own Pte Kevin Carson, who was a protestant and hated the song. Oh, how we cheered at the line: English soldiers tortured Barry, cos the names he would not tell........ Which either goes to show that we could take a joke, OR We were completely bi-partisan OR We were too thick/pissed to care;-)
