Ireland, despite being a nice place to live, has a lot of issues:
The power of the Catholic church. (finally diminishing)
Homophobia, especially in the older generation and lower class
The obsession with sport and "The Gaa, boi"
The immigration laws
The corrupt, hypocritical government
The police force - massively corrupt, and barely trained enough. Most are rude and igrnorant, no matter how you act.
The laziness - Half-assed jobs, procrastination...
The "Travelling Community" - protected by the government, despite being a group largely consisting of criminals and people of low moral. They're free to do waht they want, but if you stand up to them, you're accused of discrimination.
Lack of common sense and care among the majority of the population.
