He already own 6 guns and rifles. He is extremely proud of the fact he is a safe and responsible, registered gun owner and likes to show off pictures of his guns and shooting range practice videos to people. I told him I do not want guns in my house when we get married and he has agreed to that. This is the first big fight/debate/argument we had. We get along so well other than this and he's always shown me respect. This is the first time he treated me like an upset, irrational, unreasonable child instead of an equal. He thinks since he used to be anti-guns when he was younger, he knows everything I believe and think and because he now knows better, all my beliefs on this issue is invalid.
