Tbf we are all allowed our own opinion about accents, we don’t have to agree on what we like or don’t like.
Scottish accents vary just as English ones do, I’m English and don’t like a few accents here, and the same with Scottish accents.I don’t know where in Scotland N Sturgeon is from, but it isn’t the most attractive accent or delivery, in my own view.
I find some accents unattractive and a few hard to follow, such as the Lancashire accent of the Speaker, although it isn’t just his strong accent, again it’s the voice and manner of delivery.
