That really isn't how fully functional adults act. You should be perfectly fine knowing someone who disagrees with you. In fact, that exposes you to variety of opinions (which is good good your critical thinking abilities). Why else talk to anyone at all, if you've just surrounded yourself with only yes men, who just agree with you on everything?You can disagree with someone and still be friends, enjoy a conversation, or have other things in common. Even about politics. Even about everything.
