Any comment starting with some varient of "So you..." can almost always be ignored. I think they're framed as summarising an opponents position to lay bare an obvious flaw. But, to me aleast, they just out the commenter as being ignorant or malicious. Ignorant of what the comment they're replying to said, or maliciously trying to misrepresent it.
I think it speaks to a broader problem of online rhetoric where person X tells person Y what person Y thinks and why (and most importantly why they're wrong to think this way) instead of asking them.
Currently going through the Ender quintet, and the Expeditionary Force.
I'm on book four of the Ender series, the first two were as good as I remember. 3 an 4 have taken some work. Can't recommend buying them though as OSC is a... just the opposite of the message of the books.
Expeditionary Force is as samey as I remember. I read them as audiobooks at work so the pulp is quite welcome. Also, I'm on book 9 (not back to back reads), so while it's formulaic I guess I'm not too bored of jerking in the shower jokes. I'd recommend the first one, but not as a series.
My last "work read" was the murder bot series, I binged my way through those, pretty good
