I think you're reading waaay to much into that post. Never called Rob's character into question; merely pointed out that not betting the nuts as last to act is likely to be viewed as soft-play (which it was), regardless of the player's actual intent.I don't think anyone is suggesting that having a rulebook is not a good idea and it's not an unpopular opinion.
The unpopular part is the delivery of the previous 2 sentences. I mean, I get it but - yeesh guys. 1. It's not a tournament, so, great point? Sure? 2. Shades of soft play is a huge eye roll. I also get this one but read the room. This is a short handed table of people that are pretty friendly and Rob's the host - he's just trying not to be a dick and it was a quick decision made in the middle of the hand with not a ton of objection. I read that as an attack on character with not a ton of contextual information or a real understanding of the nature of the group of people in the room.
So we've got someone with a history of making somewhat obnoxious/cringey comments simply to broadcast their superior knowledge and you're calling OP's character into question? Yeah - that's gonna be a pretty unpopular post.
Rob gets it. No need for the white knight brigade, ffs.
