Yeah, oh well.
Most people go all ~OMG IRISH~ when they talk about Irish names, and so they give me that impression - as pretentious and trendy.
And since French, Spanish, German, and Greek all contributed to English or came from similar roots, I can understand their phonetics, even if I don't use them in everyday English. Gaelic was shut out from English's development, and so it baffles and slightly angers me on a very basic level.
Maybe my reasons aren't particularly logical, but that doesn't stop me disliking Irish names one jot.
