Well that's because SRA goes against their largely Atheistic worldview. SJW's, for the most part, hate God and especially hate Christians. They hate anything that even resembles rules or structures, things that they deem "oppressive," so naturally they hate God and his Laws. When you bring up SRA, what that says to an SJW type is "I'm a crazy Bible thumper, please mock and ridicule me." SJW's are the ultimate "if I don't personally see something take place, it never happened" people.
