One of Boswell's most credible critics was like "well actually the adelphopoesis ritual wasn't anything like marriage, it was a treaty/kinship/allegiance thing"
In this chapter he's talking about how solemn oaths between men were sometimes a treaty/kinship/allegiance thing
Him: what if this was sometimes a gay thing, on top of all the other things it could be?
Critics: what if it was NEVER a gay thing???
