This is the "evidence" for the "They want to lower the age of consent to 10!" trope
Stuart Campell (aka Wings over Scotland) takes this paragraph from a declaration from a group called "ILGA world" (who he admits he's never heard of.
1

He then notes that the World Health organisation defines adolescents as people aged between 10 to 19 and concludes, from apparently nowhere, there is only "one possible explanation"
2

He then whips out a partial list of groups who have signed up to this declaration and lo and behold, there are two Scottish organisations on it (in amongst The Labour Party, various trades unions and London councils)
3

And as these organisations get government money he concludes

"The SNP are indeed paying lobby groups with your money to try to reduce the age of consent in Scotland to 10."

IMO this whole row is based on a wilful misreading of a document and some pretty way out assumptions of what it means.
It's nasty, Fox style, Trumpian fake news aimed it stirring up hate and fear about his political opponents.

The saddest thing is that it might work

(Sorry, one mistake in the above, Campbell produces no evidence any Scottish organisation contributed or signed up to this declaration at all, just that they are members of the organisation)
