When that anthropologist or philosopher tells you that the idea of "homosexuality" is a modern concept and can't be applied to the past...
Get them to tell you a year at which the modern concept should not apply.
Most will pick somewhere around 1870 or thereabouts.
Point them at this article and tell them WRONG... 1810 at least.
