I take offense to those who are against it.
Why? I don't take offense against those who disagree with me.
You think it's because they disagree with me, and not because it's members of a privileged class dictating what I can and cannot do based on their own questionable morals?
So do you take it personally, or do you just resent them because they are keeping you from getting married?
It's both, but they're both rather tied together. Although I'm able to get married where I live, my boyfriend's home state wouldn't recognize it, and the US federal government wouldn't either.
