Exclusion and Priorities

I am very pro-life. I am also very much in favor of gay marriage. I get a lot of crap from people because of that. It seems like most people I know of who are pro-life are also against homosexuality, and those who are for gay rights are also pro-choice. I will find pro-life groups speaking out against homosexuality and gay marriage (even though the group doesn't advertise themselves as being against gay marriage), and groups that support marriage equality will speak out against restrictions on abortion (even though the group doesn't advertise themselves as being pro-choice). If they advertised themselves as a group that either fought for/against abortion and gay marriage, I'd be fine with it, but otherwise, it's annoying that they would assume that we all have the same views on other issues. Besides, if we want to end elective abortion, we should work together rather than fight about our differences. It's okay to acknowledge our differences or even to debate, as long as we're not excluding pro-lifers who have different views on other issues (except for anti-abortion terrorists. We can definitely exclude them).
I also think that people on both sides have some rather interesting priorities. I've noticed that conservative politicians will often support a constitutional amendment banning gay marriage while believing that abortion laws should be left up to the states. I've also noticed that my church (which I only go to because my parents make me) tends to focus more on ending gay marriage than ending abortion! Why is that? Is it more important to stop two people of the same gender from getting married than it is to stop the murder of unborn children?
Many liberals tend to believe that both abortion and gay marriage are essential to equality, but sometimes I wonder if they would support legalizing the abortion of gay fetuses if there were a way to test homosexuality in the womb. I mean, there are plenty of liberals who say they support women's rights, yet they still support sex-linked abortions. What's more important, marriage equality, or control over what's inside one's uterus?
What I'm trying to say is that we shouldn't exclude people from the pro-life movement, and we should make ending elective abortion our main priority. Again, it's okay to discuss our differences or even to respectfully debate, but it's not okay if it's getting in the way of what our main priority should be.
