They didn't say anything about religion - there are many non-religious anti-science views on the right, like climate denial and wild conspiracy theories. Plus, religious views that guide public policy and contradict science are fair to criticize.
I might be misreading the comment you're responding to, but I think it was describing science as a religion.
The dichotomy of "pro-science" and "anti-science" elevates science to an almost religious stature. Science is fallible, it's very hard to do and just as hard to interpret. It's also not the right tool for a lot of issues.
Increasingly people have been adopting being pro-science as a part of their identity as if science held some ultimate, unquestionable truth. To me it is akin to faith, it's an appeal to a higher authority that is used to shut down debate and paint some opinions as moral and others as immoral.
