Irish people think Gaelic is complicated because, well, frankly, English is a rather poor, simple language and by comparison Gealic is 'difficult'. I grew up speaking English and Spanish indistinctly so incorporating a third language hasn't been very hard on me, you somehow learn to make mental boxes and separate stuff. In Ireland you're bombarded by English-language media without much resistance by Gaelic speakers, so it's natural that most people would feel Gaelic to be the 'foreign' or 'nonsensical' language
Cultural assimilation has been achieved!
