"A lot of Christian today take this as both a blessing and a responsibility to care for the planet and its creatures. If we have "dominion" over for instance blue whales, if they go extinct, it is on us."

How can we have "dominion" over any living thing, apart from deciding whether we kill it or rob it of its place to live? We don't own them, you can't won a life (whatever the uber-capitalists think). The word is defined as "supreme authority" or "absolute ownership" by Miriam-Webster and there is little doubt that this is the context used in the Bible, as previously God orders man to "subdue it" (the earth) i.e. do with it as thou wilt. Little room for interpretation there.

I dunno. I don't mean to tread on the faith of most people, it's just the extremists that give such cause for concern as they attempt to impose their views on us all. Those that would teach creationism as science are indistinguishable in nature from those that practice female circumcision, ban pop music and shoot kids in the head for daring to say they should be allowed to go to school. There's an barely concealed violence about their manner and lack of tolerance that makes me think they are beyond the rules that the rest of us agree to abide by. I get from them a sense of arrogance and ignorance that is unsettling to say the least, as they fear diversity and free thought and that is truly frightening, and never ends well.
