First, what sets apart Ireland from Scotland in terms of sovereignty? Regardless of the vote, why is Ireland allowed to split, but not Scotland?

I've got no idea what you're talking about. Ireland is an independent country because that's what they wanted. Scotland HAD A VOTE and decided against it. What part of this don't you understand? who said Scotland couldn't be independent if they wanted it?

This is ridiculous. England is the seat of power of the UK; surely you know that.

Your arrogance despite a clear and total lack of understanding on the subject is astounding.

All decisions of the UK are made in England.

Yes, as that's where the UK parliament is located, however every single individual citizen of the UK has an equal vote and gets the same amount of representation as anyone else in that parliament. Our last two prime ministers were Scottish, and so were many of the top cabinet ministers of the last decade too.

The power that England has over Scotland is overwhelming.

There is no "England" in anything other than a cultural sense, as I tried explaining to you England only sends MP's to the UK parliament (who represent the whole of the nation) and they sit alongside Scottish, Welsh, N.Irish MP's. Yes there are more English MP's than those from elsewhere, that's because England has ten times bigger a population than the others. But they don't all congregate and pass laws that benefit England, I've never in my life seen that happen.

My argument is that everyone has the right to self-determination.

Your argument is a pointless one because they already have that right, as demonstrated a year ago. You never answer this point, so I'm beginning to wonder if you even know they had a vote.

Overall I'm just amazed that you think you can sit and educate someone who is half Scottish/half English and has spent equal parts of their lives in both places about how the situation is in the UK or how it's run, when I'm going to take a wild guess that you've never even been here.
