Clue: demonstrably is a word.
So after the first one of the incidents you mentioned, the FM said 'I apply the same standards to everybody. Let me be clear: no matter who they come from, I condemn any comments or language that are in any way, shape or form racist or anti-English.
That is not what my party or the movement that I am part of is for or represents. I will practise the values I hold dear, and I expect everybody to do likewise'
The second as far as I can tell, relates to something in the 90s. I would hope that maybe she has changed since then. But I don't know. If she's as bad as that suggests then they did make a big mistake with that. Presumably the party members closer to her would know though. I don't think she got elected in anyway, and there have been people, and there may well still be, in Westminster with links to terrorism. I don't see you moaning about that.
And as for the Ian Blackford tweet, it's not anglophobic to tell someone not to travel to Scotland from New Zealand in a pandemic. Even if that person happens to be English. Even if they use the words fuck off.
It's not 'whataboutery' to demonstrate that an argument is one-sided. But honestly, this is going nowhere. If the best you've got is someone telling someone not to travel in pandemic, then you've not got much.
