Perhaps you lost a friend there, because he pushed for your opinion on a matter where you disagreed. Silence-is-violence-speak is meant to scare people to agree, and when they object, like you did, it is even more harmful. Imagine two friends, with different opinions on a hot topic, leaving their opinions aside, not bringing it up, because they realize that it makes no difference. In the small world, in relations between people day to day, there is value in leaving politics out of interactions. This is fairly well established in the workplace, but I think it goes about social settings and friends too. If you push for someones opinion, be prepared to accept it as a legitimate opinion. Otherwise, don't ask for it.
