I see.

I think the comparison to The Hungry Earth/In Cold Blood is both valid and interesting, so I don't have any problem with a_cubed bringing it up. I think he also has a point that having two members of the same species represent both sides of the debate (war vs. peace/revenge vs. tolerance) had the potential for a more nuanced treatment (and I also agree its a shame the show hasn't depicted Silurians in future Earth settings). It's a shame that the Silurian story is basically just not very good otherwise I might have had more to say in reply to him beyond "I agree with everything you say" which I pretty much do.
