Why do some people oppose gay rights?
Imagine if your whole life you were taught that a specific people are evil in every way. You are totally convinced by the people you trust; family, friends, and the society you live in. Then when you meet one one of the "people", and what you were told was wrong, you would feel violated. Your entire life, an elaborate chain of lies and understandings, just falls apart. It's either fight or flight now, continue to believe despite evidence on the contrary, or reject what you were taught and use the evidence to form a new understanding. The latter is tough for some more than others. Fortunately if you were taught the scientific method, you are more likely to be malleable to the logical explanation for things.
Now for people who are against gays that are religious, well faith is a powerful tool. When you believe in something that you fear without any evidence that proves it, then you will be hard pressed to even attempt to look for evidence to disprove it. When you smash the chains of faith, then you might just get closer to accepting the logical.
-Edit- I just realized that I might of misread your statement. Sorry for the unnecessary clarification, it probably is a better answer to the original question. Unless of course the original question was posed by you.
-Edit 2- And I just realized I only needed to look to the right to see the debate creator. Sorry about that, I'm new to this site.
People normally fear anything they don't understand and fear very often turns into aggression as a form of defense. Yes, some people do, misguidedly, oppose 'gay rights' but more people have an aversion to 'gay pride' with all it's razzmatazz parades and pageantry. The gay community ''SEEM'' to be hell bent on pushing their sexual orientation down people's throats at every opportunity, and this sparks a fear in those of a nervous disposition that if the current trend continues at it's present pace it will soon become compulsory.
