I'm not sure really. I found that SRS is not nearly as interested in FPH as SRD is (note: I say "is" and not "was").  SRS mainly goes mainly for your general SJW stuff, like about women-bashing, racism, etc. I think they are more interested in groups like TRP and sexism that is upvoted in the front page submissions. SRD on the other hand is completely obsessed with fat hate. For a while when we kept hitting the front page, they could do nothing but rant and rave about the horrific skinny/fat/anorexic/ugly [add any insult here] losers we are to be so low as to hate on fat people. They still, when there is some "fat drama" as they call it happening somewhere in reddit, immediately post in there and discuss it in detail ad nauseum. Long story short, if you mention fat people are kind of gross, it touches a MASSIVE nerve with SRD.
