Yellow Ribbon:
I do not agree that wearing a yellow ribbon appropriates and repositions the purpose of the yellow ribbon. That is just pandering to the chattering classes. The man in the street won't care about the distinction.
And for me the transitive law trumps all else here “If a is equal to b and b is equal to c, then a is equal to c.” If I wear a yellow ribbon in support of Pep and Pep wears one in support of political prisoners in Spain, then I am supporting the political prisoners too.
Anyway, I hate these sort of issues, it's a bit like Brexit, you can see valid arguments on both sides.
