The clinch of love is, in its outward manifestation, much like the clinch of combat, and if we go along with the thesis of David Gilmore, combat itself is a way of cementing communal ties. Hostility, in other words, is a kind of mutuality. Language captures the paradox in that the word "hostile" has the same root as "hospitable." The host who comes to you with open arms is showing his — to use Frederic Cassidy's neologism — "hospitality."
