It doesn't change that Irish is still our language.
English is the language that we use due to coercion.
The petty remark was in relation to the amount of people who "claim" to speak some of it.
Considering it was compulsory in schools until fairly recently, I wouldn't find that unbelievable.
English is an official language too, the dominant one which is used day-to-day and understandable by the (vast) majority. History isn't really relevant.
Aye they probably know as much Irish as the average person who took German or French in school remembers, fuck all.
Nobody said otherwise.
The Irish language is the language of Ireland. As mentioned, only a certain creed would dispute that.
Also as mentioned, it is used and dominant due to coercion. Of course history is relevant.
It's Irrelevant how much you think people may remember what they learned.
