Premise: But I think marriage is a sacred institution. I'm going to be respectful for people who may disagree with me. I've had a record of doing so in the State of Texas. I've been a person that had been called a uniter, not a divider, because I accept other people's points of view.
Hypothesis: The speaker claims to be a "uniter, not a divider," because of his tolerance of other people's points of view who may not agree with him that marriage is outdated and should be abolished.
