Im gay and my friend doesnt support same sex marriage

im gay and my friend doesnt support same sex marriage. She doesnt have a problem with gays and believes they can live together but she doesnt support them getting married. I told her that we just want the same rights but she brushes it off. This has changed how I see her but I feel like im being ignorant Am I ignorant for getting a little angry and seeing her differently for not supporting same sex marriage?
