Yes, it's okay to elide international issues (perhaps to focus on one's personal interests or domestic policy and news), being neutral or taking a firm position either side.
Fortunately in the work place or with strong friendships these kinds of discussions either don't take place or take place respectfully and tactfully, without strong judgements.
My friends and I have chats on this topic, plus sectarianism in Scotland, UK immigration policy, party politics, proposed changes to the benefit system, gender rights and other sensitive topics.
None of us loses our s*it or demands that we change our stance or have to express a position.
