Well, since you've asked--

Firstly, most religious denominations do not categorically deny science. There are, in fact, many religious institutions that actually teach and advance science. Catholic Unversity of America, for instance, has reputable Departments of Biology, Physics, Mathematics, and Chemistry.

Secondly, most religious denomination do not advocate the oppression of individuals or groups.
In fact, many are actively engaged in civil and human rights activities. Martin Luther King, Jr. for instance, was a Baptist minister. And then of course there is liberation theology.

Thirdly, though there are certainly many religious persons who believe in an afterlife, for many, the concerns are primarily in the here and now, and for whom the reasons to live morally and ethically have to do with real world consequences. In a 1996 Presbyterian Panel survey only 51 percent of members and 46 percent of pastors said they believed in hell.

Even your statement about believing in a supernatural entity is up for grabs. It has been a long time since Christianity advocated that there was an actual guy walking around in the sky--St. Thomas Acquinas pretty much put that idea to rest for mainstream Christianity, and that was quite a while back.

Given that, yes, there are some people out there who believe things, advocate things, and do things that we disagree with. And it would be nice if they'd get out of our faces--
