Yes last time, still yes. Nicola Sturgeon had no choice but to go this way, due to Brexit. It's in their manifesto, as anyone who voted SNP knew, it's hardly a secret.
I don't think it's beneficial to Scotland's businesses, farming, fishing, tourism etc to come out of EU. EU citizens living in UK are already being sent 'prepare to leave' letters, having chosen to make the UK their home (in some cases for decades). Scotland needs migrant workers, they make a huge contribution. I have many EU friends who don't want to have to leave, they're happy here and are very worried.
It depends where you get your information from, I suppose. Mainstream media aren't particularly neutral on this issue. Personally, I don't think Nicola Sturgeon would have risked a 2nd referendum so soon after the first if she hadn't had some pretty clear indications from Europe as to how it would be received. If it hadn't been for Brexit, I believe 2nd ref might have happened 10-15 years down the line, with a bigger indication of potentially winning.
I would like both sides to put together a clear picture of what Brexit and Independence will look like, without the lies from last time. The value of the pound has dropped significantly Brexit vote, we've already lost business/workers.
On a side note, 'Scottish education a shambles'. Oh really? I teach in Scotland, it's not perfect by a long shot, but at least every class in Scotland has a fully qualified teacher teaching it, not a TA. Children can generally go to their local (non-selective) school, there's no scrabbling around desperately trying to find a school. No Free Schools/private franchises running schools. University education is free. Increased free nursery hours.
I don't think May has a leg to stand on. Brexit is by far the most divisive and destructive political act in my lifetime.
