Assuredly? Hmmm.... not a word I would have thought of for this context. Anyway...
People are drawn together by commonalities. That's how we make friends. A person's friend is usually someone with whom they have a lot in common with (positive or negative) - liking the same music, disliking the same foods, liking the same celebrity, disliking teh same celebrity, having the same political beliefs, having the same hobbies, etc. Usually, the positive commonalities are stronger than the negative ones. For example, A friendship based solely upon both parties liking to crochet, will probably be stronger than one based on both parties hating beets.
