I admit I don't know much about him, not being into streamer culture. I assumed him not to be a piece of shit, which admittedly may not be a safe assumption as far as gaming goes.
I scanned the thread (and the entirety of this page) and found no mention of any other reason for him to exclude female streamers than what he stated. I may have missed it, so if you can point me to it, I'll be happy to educate myself.
That said, I don't understand why the thread is talking about how flimsy his explanation is or isn't, if he's literally contradicting a prior statement. Why not focus on that instead? I mean, if he's said in the past "I don't stream with women because X", then that's pretty much checkmate and all speculation is pointless, isn't it?
