No. Conservatives pretend that they object to social issues for reasons that they don't actually care that much about ("marriage is between a man and a woman!")
On that issue, I'd agree. Of course, I'm pro-gay rights, and I know that a lot of conservatives around here are against gay marriage because they hate homosexuals and homosexuality; plain and simple. The same would go for conservatives who want creation taught in public schools. They say they want creation to be given equal time with evolution, but in reality, they want a religious point of view pushed onto public school students, some of whom may be unsuspecting.
BUT, there are certainly social issues that we (conservatives) care deeply about and have no hidden agenda on. Abortion and gun control would be two that immediately come to mind.
