Basically this TMGM guy claimed that people who didn't like SGU and didn't watch it beyond the first episodes just weren't open-minded to change - another one of the subtle digs at SGA and SG1 fans, as if there were something wrong with them and not with the show. And completely ignoring the fact that many Stargate fans did in fact give SGU a chance to start with but gave up at some point.
Before Uxmal tackled that post, Cimmer had a brilliant response to it (Uxmal praised it in his post). Very civil, as is usually the case for her, but also very to the point.
Like I said before, I messed up and lost it, so I'll post the only bits that I have found. If the rest pops up I'll post it here, because it is an excellent read.
Unfortunately that's all I have for now (more will come). But it's enough to show that it was indeed wrong IMO for the mods to delete that comment in particular. Cimmer is neither addressing TMGM nor flaming him - she just refutes the merits (i.e. the lack thereof) of his argument.
