Sorry, I cannot cope with talking through a veil to someone I may or may not know. I can't be bothered with cuteness.
Plus, I'm about to be away from my computer for a week, so cannot properly develop a debate.
However, Archie's stance during the Holy Loch protests was itself I think a political statement - not however one that would then have barred him from the US, any more than my actions of the time would have barred me, by the way.
The collaborative work he did with John MacGrath more recently, and some comments he made to me at that time, were political statements that would be considered less welcome in the current US climate.
And both of us had / have various other friendships, and have been involved in various collaborative stances, that would tag our US files as 'suspect, better refuse'.
