No, no, you don't understand.
Being on one side of a debate that splits opinion roughly 50/50 = toxic and divisive.
Being part of the other half of that debate = not toxic and divisive at all.
'toxic and divisive' is nothing more than a jingoistic unionist mantra, because they know they can't mount any credible argument against the perfectly normal, rational, and entirely common place phenomenon of self-governance. So all that's left is to bandy about ridiculous terms that don't stand up to scrutiny.
All politics is 'divisive' by nature, because, newsflash, people have differences of opinion. What unionists actually mean when they carp on about 'divisive', is 'you disagree with us. Sit down, shut up, get back in your box because you're making us uncomfortable'.
Sorry, ain't going to happen. The irony is, it's invariably from the same types who rant endlessly about people being 'cancelled', and 'wokery'.
The hypocrisy and total lack of self-awareness is astounding.
